=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 $message_headers.
+exipick is a tool to display messages in an Exim queue. It is very similar to exiqgrep and is, in fact, a drop in replacement for exiqgrep. exipick allows you to select messages to be displayed using any piece of data stored in an Exim spool file. Matching messages can be displayed in a variety of formats.
+
+=head1 QUICK START
+
+Delete every frozen message from queue:
+ exipick -zi | xargs exim -Mrm
+
+Show only messages which have not yet been virus scanned:
+ exipick '$received_protocol ne virus-scanned'
+
+Run the queue in a semi-random order:
+ exipick -i --random | xargs exim -M
+
+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'
+
+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 \
+ '$received_port == 587'
+
+Display only messages whose every recipient is in the example.com domain, also listing the IP address of the sending host:
+ exipick --show-vars sender_host_address \
+ '$each_recipients = example.com'
+
+Same as above, but show values for all defined variables starting with sender_ and the number of recipients:
+ exipick --show-vars ^sender_,recipients_count \
+ '$each_recipients = example.com'
=head1 OPTIONS
=over 4
-=item --spool
+=item --and
-The path to Exim's spool directory. In general usage you should set the $spool variable in the script to your site's main spool directory (and if exipick was installed from the Exim distribution, this is done by default), but this option is useful for alternate installs, or installs on NFS servers, etc.
+Display messages matching all criteria (default)
-=item --and
+=item -b
-A message will be displayed only if it matches all of the specified criteria. This is the default.
+Display messages in brief format (exiqgrep)
-=item --or
+=item -bp
-A message will be displayed if it matches any of the specified criteria.
+Display messages in standard mailq format (default)
-=item --caseful
+=item -bpa
-By default criteria using the '=' operator are caseless. Specifying this option make them respect case.
+Same as -bp, show generated addresses also (exim)
-=item --show-vars <variable>[,<variable>...]
+=item -bpc
-Cause the value of each specified variable to be displayed for every message dispayed. For instance, the command "exipick --show-vars '$sender_ident' 'sender_host_address eq 127.0.01'" will show the ident string for every message submitted via localhost. How exactly the variable value is diplayed changes according to what output format you specify.
+Show a count of matching messages (exim)
-=item --show-rules
+=item -bpr
+
+Same as '-bp --unsorted' (exim)
-If specified the internal representation of each message criteria is shown. This is primarily used for debugging purposes.
+=item -bpra
+
+Same as '-bpr --unsorted' (exim)
+
+=item -bpru
+
+Same as '-bpu --unsorted' (exim)
+
+=item -bpu
+
+Same as -bp, but only show undelivered messages (exim)
+
+=item -c
+
+Show a count of matching messages (exiqgrep)
+
+=item --caseful
-==item --show-tests
+Make operators involving '=' honor case
-If specified, for every message (regardless of matching criteria) the criteria's actual value is shown and the compiled internal eval is shown. This is used primarily for debugging purposes.
+=item --charset
+
+Override the default local character set for $header_ decoding
+
+=item -f <regexp>
+
+Same as '$sender_address = <regexp>' (exiqgrep)

+Display messages in reverse order
-=item <criterion>
+=item -s <string>
-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 '$shown_message_size eq <string>' (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 --spool <path>
-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')

-=item --version

-=back
+=item --show-vars <variable>[,<variable>...]
-=head1 VARIABLE TYPES
+Show the value for <variable> for each displayed message. <variable> will be a regular expression if it begins with a circumflex.
-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 --size
-=over 4
+Show the total bytes used by each displayed message
-=item NUMERIC
+=item --thaw <cache file>
-Variable of the numeric type can be of integer or float. Valid comparisons are <, <=, >, >=, ==, and !=.
+Read queue information cached from a previous --freeze run
-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: '$message_age >= 3K'.
+=item --sort <variable>[,<variable>...]
-=item BOOLEAN
+Display matching messages sorted according to <variable>
-Variables of the boolean type are very easy to use in criteria. The format is either the variable by itself or the variable negated with a ! sign. For instance, '$deliver_freeze' matches if the message in question is frozen, '!$deliver_freeze' matches if message is not frozen.
+=item --unsorted
-=item STRING
+Do not apply any sorting to output
+
+=item --version
+
+Display the version of this command
-String variables are basically defined as those that are neither numeric nor boolean and can contain any data. The string operators are =, eq, ne, =~, and !~. With the exception of '=', the operators all match the functionality of the like-named perl operators.
+=item -x
-The simplest form is a bare string regular expression, represented by the operator '='. The value used for the comparison will be evaluated as a regular expression and can be as simple or as complex as desired. For instance '$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 '!$deliver_freeze' (exiqgrep)
-Slightly more complex is the string comparison with the operators 'eq' and 'ne' for equal and not equal, respectively. '$sender_helo_name eq hotmail.com' is true for messages with the exact helo string "hotmail.com", while '$sender_helo_name ne hotmail.com' is true for any message with a helo string other than "hotmail.com".
+=item -y
-The most complex and the most flexible format are straight regular expressions with the operators '=~' and '!~'. The value in the criteria is expected to be a correctly formatted perl regular expression B<including the regexp delimiters (usually //)>. The criterion '$sender_helo_name !~ /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/' matches for any message which does not have an IP address for its helo string.
+Same as '$message_age < <seconds>' (exiqgrep)
+
+=item -z
+
+Same as '$deliver_freeze' (exiqgrep)

-=head1 VARIABLES
+=head1 CRITERIA
-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, $sender_host_port is not defined for messages not received from a remote host.
+Exipick decides which messages to display by applying a test against each message. The rules take the general form of 'VARIABLE OPERATOR VALUE'. For example, '$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.
+
+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.
-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.
+See the VARIABLES and OPERATORS sections below for more details
-=head2 Boolean variables
+=head1 OPERATORS
=over 4
-=item + $allow_unqualified_recipient
+=item BOOLEAN
-TRUE if unqualified recipient addresses are permitted in header lines.
+Boolean variables are checked simply by being true or false. There is no real operator except negation. Examples of valid boolean tests:
+ '$deliver_freeze'
+ '!$deliver_freeze'
-=item + $allow_unqualified_sender
+=item NUMERIC
-TRUE if unqualified sender addresses are permitted in header lines.
+Valid comparisons are <, <=, >, >=, ==, and !=. Numbers can be integers or floats. Any number in a test suffixed with d, h, m, s, M, K, or B will be mulitplied by 86400, 3600, 60, 1, 1048576, 1024, or 1 respectively. Examples of valid numeric tests:
+ '$message_age >= 3d'
+ '$local_interface == 587'
+ '$message_size < 30K'
-=item + $deliver_freeze
+=item STRING
-TRUE if the message is currently frozen.
+The string operators are =, eq, ne, =~, and !~. With the exception of '=', the operators all match the functionality of the like-named perl operators. eq and ne match a string exactly. !~, =~, and = apply a perl regular expression to a string. The '=' operator behaves just like =~ but you are not required to place // around the regular expression. Examples of valid string tests:
+ '$received_protocol eq esmtp'
+ '$sender_address = example.com'
+ '$each_recipients =~ /^a[a-z]{2,3}@example.com$/'
-=item . $first_delivery
+=item NEGATION
-TRUE if the message has never been deferred.
+There are many ways to negate tests, each having a reason for existing. Many tests can be negated using native operators. For instance, >1 is the opposite of <=1 and eq and ne are opposites. In addition, each individual test can be negated by adding a ! at the beginning of the test. For instance, '!$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 . $manually_thawed
+=back
-TRUE when the message has been manually thawed.

-TRUE if, under normal circumstances, Exim will not try to deliver the message.
+Internally, all variables are represented as strings, meaning any operator will work on any variable.

-=head1 ACKNOWLEDGEMENTS
-
-Although I conceived of the concept for this program independently, the name 'exipick' was taken from the Exim WishList and was suggested by Jeffrey Goldberg.
-
-Thank you to Philip Hazel for writing Exim. Of course this program exists because of Exim, but more specifically the message parsing code is based on Exim's and some of this documentation was copy/pasted from Exim's.
