=head1 NAME
-exipick - display messages from Exim queue based on a variety of criteria
+exipick - selectively display messages from an Exim queue
-=head1 USAGE
+=head1 SYNOPSIS
-exipick [--help|--version] | [-spool <spool>] [-and|-or] [-bp|-bpa|-bpc|-bpr|-bpra|-bpru|-bpu] [<criterion> [<criterion> ...]]
+exipick [<options>] [<criterion> [<criterion> ...]]
=head1 DESCRIPTION
-exipick is designed to display the contents of a Exim mail spool based on user-specified criteria. It is designed to mimic the output of 'exim -bp' (or any of the other -bp* options) and Exim's spec.txt should be used to learn more about the exact format of the output. The criteria are formed by creating comparisons against characteristics of the messages, for instance $message_size, $sender_helo_name, or $message_headers.
+exipick is a tool to display messages in an Exim queue. It is very similar to exiqgrep and is, in fact, a drop in replacement for exiqgrep. exipick allows you to select messages to be displayed using any piece of data stored in an Exim spool file. Matching messages can be displayed in a variety of formats.
-=head1 OPTIONS
+=head1 QUICK START
-=over 4
+Delete every frozen message from queue:
+ exipick -zi | xargs exim -Mrm
-=item --spool
+Show only messages which have not yet been virus scanned:
+ exipick '$received_protocol ne virus-scanned'
-The path to Exim's spool directory. In general usage you should set the $spool variable in the script to your site's main spool directory (and if exipick was installed from the Exim distribution, this is done by default), but this option is useful for alternate installs, or installs on NFS servers, etc.
+Run the queue in a semi-random order:
+ exipick -i --random | xargs exim -M
-=item --and
+Show the count and total size of all messages which either originated from localhost or have a received protocol of 'local':
+ exipick --or --size --bpc \
+ '$sender_host_address eq 127.0.0.1' \
+ '$received_protocol eq local'
-A message will be displayed only if it matches all of the specified criteria. This is the default.
+Display all messages received on the MSA port, ordered first by the sender's email domain and then by the size of the emails:
+ exipick --sort sender_address_domain,message_size \
+ '$interface_port == 587'
-=item --or
+Display only messages whose every recipient is in the example.com domain, also listing the IP address of the sending host:
+ exipick --show-vars sender_host_address \
+ '$each_recipients = example.com'
-A message will be displayed if it matches any of the specified criteria.
+=head1 OPTIONS
-=item --caseful
+=over 4
-By default criteria using the '=' operator are caseless. Specifying this option make them respect case.
+=item --and
-=item The -bp* options all control how much information is displayed and in what manner. They all match the functionality of the options of the same name in Exim. Briefly:
+Display messages matching all criteria (default)
-=item -bp display the matching messages in 'mailq' format.
+=item -b
-=item -bpa ... with generated addresses as well.
+Display messages in brief format (exiqgrep)
-=item -bpc ... just show a count of messages.
+=item -bp
-=item -bpr ... do not sort.
+Display messages in standard mailq format (default)
-=item -bpra ... with generated addresses, unsorted.
+=item -bpa
-=item -bpru ... only undelivered addresses, unsorted.
+Same as -bp, show generated addresses also (exim)
-=item -bpu ... only undelivered addresses.
+=item -bpc
-Please see Exim's spec.txt for details on the format and information displayed with each option.
+Show a count of matching messages (exim)
-=item The following options are included for compatibility with the 'exiqgrep' utility:
+=item -bpr
-=item -f <regexp> Same as '$sender_address = <regexp>'
+Same as '-bp --unsorted' (exim)
-=item -r <regexp> Same as '$recipients = <regexp>'
+=item -bpra
-=item -y <seconds> Same as '$message_age < <seconds>'
+Same as '-bpr --unsorted' (exim)
-=item -o <seconds> Same as '$message_age > <seconds>'
+=item -bpru
-=item -z Same as '$deliver_freeze'
+Same as '-bpu --unsorted' (exim)
-=item -x Same as '!$deliver_freeze'
+=item -bpu
-=item -c Display count of matches only
+Same as -bp, but only show undelivered messages (exim)
-=item -l Display in long format (default)
+=item -c
-=item -i Display message IDs only
+Show a count of matching messages (exiqgrep)
-=item -b Display brief format only
+=item --caseful
-Please see the 'exiqgrep' documentation for more details on the behaviour and output format produced by these options
+Make operators involving '=' honor case
-=item <criterion>
+=item -f <regexp>
-The criteria are used to determine whether or not a given message should be displayed. The criteria are built using variables containing information about the individual messages (see VARIABLES section for list and descriptions of available variables). Each criterion is evaluated for each message in the spool and if all (by default) criteria match or (if --or option is specified) any criterion matches, the message is displayed. See VARIABLE TYPES for explanation of types of variables and the evaluations that can be performed on them and EXAMPLES section for complete examples.
+Same as '$sender_address = <regexp>' (exiqgrep)
-The format of a criterion is explained in detail below, but a key point to make is that the variable being compared must always be on the left side of the comparison.
+=item --flatq
-If no criteria are provided all messages in the queue are displayed (in this case the output of exipick should be identical to the output of 'exim -bp')
+Use a single-line output format
-=item --help
+=item --freeze <cache file>
-This screen.
+Save queue information in an quickly retrievable format
-=item --version
+=item --help
-Version info.
+Display this output
-=back
+=item -i
-=head1 VARIABLE TYPES
+Display only the message IDs (exiqgrep)
-Although there are variable types defined, they are defined only by the type of data that gets put into them. They are internally typeless. Because of this it is perfectly legal to perform a numeric comparison against a string variable, although the results will probably be meaningless.
+=item -l
-=over 4
+Same as -bp (exiqgrep)
-=item NUMERIC
+=item --not
-Variable of the numeric type can be of integer or float. Valid comparisons are <, <=, >, >=, ==, and !=.
+Negate all tests.
-The numbers specified in the criteria can have a suffix of d, h, m, s, M, K, or B, in which case the number will be mulitplied by 86400, 3600, 60, 1, 1048576, 1024, or 1 respectively. These suffixes are case sensitive. While these are obviously designed to aid in date and size calculations, they are not restricted to variables of their respective types. That is, though it's odd it's legal to create a criterion of a message being around for 3 kiloseconds: '$message_age >= 3K'.
+=item -o <seconds>
-=item BOOLEAN
+Same as '$message_age > <seconds>' (exiqgrep)
-Variables of the boolean type are very easy to use in criteria. The format is either the variable by itself or the variable negated with a ! sign. For instance, '$deliver_freeze' matches if the message in question is frozen, '!$deliver_freeze' matches if message is not frozen.
+=item --or
-=item STRING
+Display messages matching any criteria
-String variables are basically defined as those that are neither numeric nor boolean and can contain any data. The string operators are =, eq, ne, =~, and !~. With the exception of '=', the operators all match the functionality of the like-named perl operators.
+=item -R
-The simplest form is a bare string regular expression, represented by the operator '='. The value used for the comparison will be evaluated as a regular expression and can be as simple or as complex as desired. For instance '$sender_helo_name = example' on the simple end or '$sender_helo_name = ^aol\.com$' on the more complex end. This comparison is caseless by default, but see the --caseful option to change this.
+Same as --reverse (exiqgrep)
-Slightly more complex is the string comparison with the operators 'eq' and 'ne' for equal and not equal, respectively. '$sender_helo_name eq hotmail.com' is true for messages with the exact helo string "hotmail.com", while '$sender_helo_name ne hotmail.com' is true for any message with a helo string other than "hotmail.com".
+=item -r <regexp>
-The most complex and the most flexible format are straight regular expressions with the operators '=~' and '!~'. The value in the criteria is expected to be a correctly formatted perl regular expression B<including the regexp delimiters (usually //)>. The criterion '$sender_helo_name !~ /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/' matches for any message which does not have an IP address for its helo string.
+Same as '$recipients = <regexp>' (exiqgrep)
-=back
+=item --random
-=head1 VARIABLES
+Display messages in random order
-With a few exceptions the available variables match Exim's internal expansion variables in both name and exact contents. There are a few notable additions and format deviations which are noted below. Although a brief explanation is offered below, Exim's spec.txt should be consulted for full details. It is important to remember that not every variable will be defined for every message. For example, $sender_host_port is not defined for messages not received from a remote host.
+=item --reverse
-In the list below, '.' denotes standard messages with contents matching Exim's variable, '#' denotes standard variables with non-standard contents, and '+' denotes a non-standard variable.
+Display messages in reverse order
-=head2 Boolean variables
+=item -s <string>

+Show the total bytes used by each displayed message
-=item + $dont_deliver

-TRUE if, under normal circumstances, Exim will not try to deliver the message.
+Read queue information cached from a previous --freeze run
-=item . $host_lookup_deferred
+=item --sort <variable>[,<variable>...]
-TRUE if there was an attempt to look up the host's name from its IP address, but an error occurred that during the attempt.
+Display matching messages sorted according to <variable>
-=item . $host_lookup_failed
+=item --unsorted
-TRUE if there was an attempt to look up the host's name from its IP address, but the attempt returned a negative result.
+Do not apply any sorting to output
-=item + $local_error_message
+=item --version
-TRUE if the message is a locally-generated error message.
+Display the version of this command
-=item + $sender_local
+=item -x
-TRUE if the message was locally generated.
+Same as '!$deliver_freeze' (exiqgrep)
-=item + $sender_set_untrusted
+=item -y
-TRUE if the envelope sender of this message was set by an untrusted local caller.
+Same as '$message_age < <seconds>' (exiqgrep)
-=item . $tls_certificate_verified
+=item -z
-TRUE if a TLS certificate was verified when the message was received.
+Same as '$deliver_freeze' (exiqgrep)
=back
-=head2 Numeric variables
+=head1 CRITERIA
-=over 4
+Exipick decides which messages to display by applying a test against each message. The rules take the general form of 'VARIABLE OPERATOR VALUE'. For example, '$message_age > 60'. When exipick is deciding which messages to display, it checks the $message_age variable for each message. If a message's age is greater than 60, the message will be displayed. If the message's age is 60 or less seconds, it will not be displayed.
-=item . $body_linecount
+Multiple criteria can be used. The order they are specified does not matter. By default all criteria must evaluate to true for a message to be displayed. If the --or option is used, a message is displayed as long as any of the criteria evaluate to true.
-The number of lines in the message's body.
+See the VARIABLES and OPERATORS sections below for more details
-=item . $body_zerocount
+=head1 OPERATORS
-The number of binary zero bytes in the message's body.
+=over 4
-=item + $deliver_frozen_at
+=item BOOLEAN
-The epoch time at which message was frozen.
+Boolean variables are checked simply by being true or false. There is no real operator except negation. Examples of valid boolean tests:
+ '$deliver_freeze'
+ '!$deliver_freeze'
-=item . $interface_port
+=item NUMERIC
-The local port number if network-originated messages.
+Valid comparisons are <, <=, >, >=, ==, and !=. Numbers can be integers or floats. Any number in a test suffixed with d, h, m, s, M, K, or B will be mulitplied by 86400, 3600, 60, 1, 1048576, 1024, or 1 respectively. Examples of valid numeric tests:
+ '$message_age >= 3d'
+ '$local_interface == 587'
+ '$message_size < 30K'
-=item . $message_age
+=item STRING
-The number of seconds since the message was received.
+The string operators are =, eq, ne, =~, and !~. With the exception of '=', the operators all match the functionality of the like-named perl operators. eq and ne match a string exactly. !~, =~, and = apply a perl regular expression to a string. The '=' operator behaves just like =~ but you are not required to place // around the regular expression. Examples of valid string tests:
+ '$received_protocol eq esmtp'
+ '$sender_address = example.com'
+ '$each_recipients =~ /^a[a-z]{2,3}@example.com$/'
-=item . $message_body_size
+=item NEGATION
-The size of the body in bytes.
+There are many ways to negate tests, each having a reason for existing. Many tests can be negated using native operators. For instance, >1 is the opposite of <=1 and eq and ne are opposites. In addition, each individual test can be negated by adding a ! at the beginning of the test. For instance, '!$acl_m1 =~ /^DENY$/' is the same as '$acl_m1 !~ /^DENY$/'. Finally, every test can be specified by using the command line argument --not. This is functionally equivilant to adding a ! to the beginning of every test.
-=item . $message_size
+=back
-The size of the message in bytes.
+=head1 VARIABLES
-=item . $originator_gid
+With a few exceptions the available variables match Exim's internal expansion variables in both name and exact contents. There are a few notable additions and format deviations which are noted below. Although a brief explanation is offered below, Exim's spec.txt should be consulted for full details. It is important to remember that not every variable will be defined for every message. For example, $sender_host_port is not defined for messages not received from a remote host.
-The group id under which the process that called Exim was running as when the message was received.
+Internally, all variables are represented as strings, meaning any operator will work on any variable. This means that '$sender_host_name > 4' is a legal criterion, even if it does not produce meaningful results. Variables in the list below are marked with a 'type' to help in choosing which types of operators make sense to use.
-=item . $originator_uid
+ Identifiers
+ B - Boolean variables
+ S - String variables
+ N - Numeric variables
+ . - Standard variable matching Exim's content definition
+ # - Standard variable, contents differ from Exim's definition

-The user id under which the process that called Exim was running as when the message was received.
+=over 4
-=item . $received_count
+=item S . $acl_c0-$acl_c9, $acl_m0-$acl_m9
-The number of Received: header lines in the message.
+User definable variables.
-=item + $received_time
+=item B + $allow_unqualified_recipient
-The epoch time at which the message was received.
+TRUE if unqualified recipient addresses are permitted in header lines.

+=item B + $allow_unqualified_sender
-The number of envelope recipients for the message.
+TRUE if unqualified sender addresses are permitted in header lines.
-=item + $recipients_del_count
+=item S . $authenticated_id
-The number of envelope recipients for the message which have already been delivered. Note that this is the count of original recipients to which the message has been delivered. It does not include generated addresses so it is possible that this number will be less than the number of addresses in the recipients_del string.
+Optional saved information from authenticators, or the login name of the calling process for locally submitted messages.
-=item + $recipients_undel_count
+=item S . $authenticated_sender
-The number of envelope recipients for the message which have not yet been delivered.
+The value of AUTH= param for smtp messages, or a generated value from the calling processes login and qualify domain for locally submitted messages.
-=item . $sender_host_port
+=item S + $bmi_verdicts
-The port number that was used on the remote host for network-originated messages.
+The verdict string provided by a Brightmail content scan
-=item + $warning_count
+=item N . $body_linecount
-The number of delay warnings which have been sent for this message.

-Optional saved information from authenticators, or the login name of the calling process for locally submitted messages.
+=item B + $dont_deliver
-=item . $authenticated_sender
+TRUE if, under normal circumstances, Exim will not try to deliver the message.
-The value of AUTH= param for smtp messages, or a generated value from the calling processes login and qualify domain for locally submitted messages.
+=item S + $each_recipients
-=item + $bmi_verdicts
+This is a psuedo variable which allows you to apply a test against each address in $recipients individually. Whereas '$recipients =~ /@aol.com/' will match if any recipient address contains aol.com, '$each_recipients =~ /@aol.com$/' will only be true if every recipient matches that pattern. Note that this obeys --and or --or being set. Using it with --or is very similar to just matching against $recipients, but with the added benefit of being able to use anchors at the beginning and end of each recipient address.
-I honestly don't know what the format of this variable is. It only exists if you have Exim compiled with WITH_CONTENT_SCAN and EXPERIMENTAL_BRIGHTMAIL (and, you know, pay Symantec/Brightmail a bunch of money for the client libs and a server to use them with).
+=item S + $each_recipients_del
-=item + $each_recipients
+Like $each_recipients, but for $recipients_del
-This is a psuedo variable which allows you to apply a criterion against each address in $recipients individually. This allows you to create criteria against which every individual recipient is tested. For instance, '$recipients =~ /aol.com/' will match if any of the recipient addresses contain the string "aol.com". However, with the criterion '$each_recipients =~ /@aol.com$/', a message will only match if B<every> recipient matches that pattern. Note that this obeys --and or --or being set. Using it with --or is very similar to just matching against $recipients, but with the added benefit of being able to use anchors at the beginning and end of each recipient address.
