=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
+
+Display messages matching all criteria (default)
-The path to Exim's spool directory. In general usage you should set the $spool variable in the script to your site's main spool directory (and if exipick was installed from the Exim distribution, this is done by default), but this option is useful for alternate installs, or installs on NFS servers, etc.
+=item -b
-=item --and
+Display messages in brief format (exiqgrep)
-A message will be displayed only if it matches all of the specified criteria. This is the default.
+=item -bp
-=item --or
+Display messages in standard mailq format (default)
+
+=item -bpa
-A message will be displayed if it matches any of the specified criteria.
+Same as -bp, show generated addresses also (exim)
+
+=item -bpc
+
+Show a count of matching messages (exim)
+
+=item -bpr
+
+Same as '-bp --unsorted' (exim)
+
+=item -bpra
+
+Same as '-bpa --unsorted' (exim)
+
+=item -bpru
+
+Same as '-bpu --unsorted' (exim)
+
+=item -bpu
+
+Same as -bp, but only show undelivered messages (exim)
+
+=item -C | --config <config>
+
+Use <config> to determine the proper spool directory. (See C<--spool>
+or C<--input> for alternative ways to specify the directories to operate on.)
+
+=item -c
+
+Show a count of matching messages (exiqgrep)
=item --caseful
-By default criteria using the '=' operator are caseless. Specifying this option make them respect case.
+Make operators involving '=' honor case
-=item --show-vars <variable>[,<variable>...]
+=item --charset
-Cause the value of each specified variable to be displayed for every message dispayed. For instance, the command "exipick --show-vars '$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.
+Override the default local character set for $header_ decoding
-=item --show-rules
+=item -f <regexp>
-If specified the internal representation of each message criteria is shown. This is primarily used for debugging purposes.
+Same as '$sender_address =~ /<regexp>/' (exiqgrep). Note that this preserves the default case sensitivity of exiqgrep's interface.
-==item --show-tests
+=item --finput
-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.
+Same as '--input-dir Finput'. 'Finput' is where exim copies frozen messages when compiled with SUPPORT_MOVE_FROZEN_MESSAGES.
=item --flatq
-Change format of output so that every message is on a single line. Useful for parsing with tools such as sed, awk, cut, etc.
+Use a single-line output format
-=item --unsorted
+=item --freeze <cache file>
-This prevents sorting the messages according to their age when they are displayed. While there were exim-clone options that enabled this functionality (-bpr, -bpra, etc) they only worked in the standard output format. --unsorted works in all output formats, including the exiqgrep clone output and --flatq.
+Save queue information in an quickly retrievable format
+
+=item --help
-=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 this output
-=item -bp display the matching messages in 'mailq' format.
+=item -i
-=item -bpa ... with generated addresses as well.
+Display only the message IDs (exiqgrep)
-=item -bpc ... just show a count of messages.
+=item --input-dir <inputname>
-=item -bpr ... do not sort.
+Set the name of the directory under the spool directory. By default this is "input". If this starts with '/', the value of --spool is ignored. See also --finput.
-=item -bpra ... with generated addresses, unsorted.
+=item -l
-=item -bpru ... only undelivered addresses, unsorted.
+Same as -bp (exiqgrep)
-=item -bpu ... only undelivered addresses.
+=item --not
-Please see Exim's spec.txt for details on the format and information displayed with each option.
+Negate all tests.
-=item The following options are included for compatibility with the 'exiqgrep' utility:
+=item -o <seconds>
-=item -f <regexp> Same as '$sender_address = <regexp>'
+Same as '$message_age > <seconds>' (exiqgrep)
-=item -r <regexp> Same as '$recipients = <regexp>'
+=item --or
-=item -s <string> Same as '$shown_message_size eq <string>'
+Display messages matching any criteria
-=item -y <seconds> Same as '$message_age < <seconds>'
+=item -R
-=item -o <seconds> Same as '$message_age > <seconds>'
+Same as --reverse (exiqgrep)
-=item -z Same as '$deliver_freeze'
+=item -r <regexp>
-=item -x Same as '!$deliver_freeze'
+Same as '$recipients =~ /<regexp>/' (exiqgrep). Note that this preserves the default case sensitivity of exiqgrep's interface.
-=item -c Display count of matches only
+=item --random
-=item -l Display in long format (default)
+Display messages in random order
-=item -i Display message IDs only
+=item --reverse
-=item -b Display brief format only
+Display messages in reverse order
-Please see the 'exiqgrep' documentation for more details on the behaviour and output format produced by these options
+=item -s <string>
-=item <criterion>
+Same as '$shown_message_size eq <string>' (exiqgrep)
-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.
+=item --spool <path>
-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.
+Set the path to the exim spool to use. This value will have the argument to --input or 'input' appended, or be ignored if --input is a full path. If not specified, exipick uses the value from C<exim [-C config] -n -bP spool_directory>, and if this call fails, the F</opt/exim/spool> from build time (F<Local/Makefile>) is used. See also --config.
-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 --show-rules
-=item --freeze <cache file>, --thaw <cache file>
+Show the internal representation of each criterion specified
-Every time exipick runs, it has to rescan the input directory, open every file, and correctly parse the contents of every file. While this isn't very time consuming on with a small queue or a lightly loaded server, it can take a great deal of time on heavily loaded machines or large queues. Unfortunately, one of the best times to use exipick is diagnosing large mail queues.
+=item --show-tests
-To speed run times in these situations, you can use --freeze to save a cache of the message information. --thaw can then be used to read from the cache rather than directly from the spool. Over time, of course, the information in the cache will drift further and further out of date, but this is not a significant problem over short runs, but do keep in mind that any deliveries made or messages removed from the queue after the cache file is made will not be reflected in the output when using --thaw.
+Show the result of each criterion on each message
-All message variables are saved to the cache except $message_body and $message_age. $message_age is skipped because it is recalculated dynamically at every running of exipick. $message_body is skipped because of the potentially large storage requirements. If $message_body is referenced in any criteria when using --thaw, the data will be looked up from the spool file if the message is still in the spool.
+=item --show-vars <variable>[,<variable>...]
-If criteria are specified when using --freeze, only matching messages will be written to the cache file. Subsequent runs of exipick --thaw using that cache file will not need the original criteria specified.
+Show the value for <variable> for each displayed message. <variable> will be a regular expression if it begins with a circumflex.
-There are tradeoffs when using this system, time and space. The cache file will take disk space to write. The size of the file depends on the type of mail the server handles, but it ranges between 2KB and 5KB per message. The run of exipick which creates the cache file will take longer to run than a standard run, perhaps as much as 50% longer, but the subsequent runs readng from the cache file will take as little as 10-20% of the time it would take for a run of exipick without --freeze/--thaw. In other words, if a system is in a state where it takes 30 seconds to run exipick, making a cache file will take around 45 second, but subsequent reads of the cache will take around 5 seconds. The size needed for the cache file decrease and the performance gains on the --thaw runs increase if criteria which limits the number of messages written to the cache file are used on the --freeze run.

-=head1 VARIABLE TYPES
+=head1 CRITERIA
-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.
+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 $message_age variable for each message. If a message's age is greater than 60, the message will be displayed. If the message's age is 60 or less seconds, it will not be displayed.
-=over 4
+Multiple criteria can be used. The order they are specified does not matter. By default all criteria must evaluate to true for a message to be displayed. If the --or option is used, a message is displayed as long as any of the criteria evaluate to true.
-=item NUMERIC
+See the VARIABLES and OPERATORS sections below for more details
-Variable of the numeric type can be of integer or float. Valid comparisons are <, <=, >, >=, ==, and !=.
+=head1 OPERATORS
-The numbers specified in the criteria can have a suffix of d, h, m, s, M, K, or B, in which case the number will be mulitplied by 86400, 3600, 60, 1, 1048576, 1024, or 1 respectively. These suffixes are case sensitive. While these are obviously designed to aid in date and size calculations, they are not restricted to variables of their respective types. That is, though it's odd it's legal to create a criterion of a message being around for 3 kiloseconds: '$message_age >= 3K'.
+=over 4
=item BOOLEAN
-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.
+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 STRING
-
-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 NUMERIC
-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$' on the more complex end. This comparison is caseless by default, but see the --caseful option to change this.
+Valid comparisons are <, <=, >, >=, ==, and !=. Numbers can be integers or floats. Any number in a test suffixed with d, h, m, s, M, K, or B will be multiplied by 86400, 3600, 60, 1, 1048576, 1024, or 1 respectively. Examples of valid numeric tests:
+ '$message_age >= 3d'
+ '$local_interface == 587'
+ '$message_size < 30K'
-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 STRING
-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.
+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 NEGATION
-In addition to standard logical negation available with the operators above (== vs !=, < vs >=, etc) any criteria can be whole negated by prepending an exclamation mark ("!") to the variable name. This is required for negating boolean variables, and very convenient for negating the simple '=' operator (previously, the opposite of '$var = foo' was '$var !~ /foo/'. This can now be written '!$var = foo').
+There are many ways to negate tests, each having a reason for existing. Many tests can be negated using native operators. For instance, >1 is the opposite of <=1 and eq and ne are opposites. In addition, each individual test can be negated by adding a ! at the beginning of the test. For instance, '!$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 equivalent to adding a ! to the beginning of every test.
=back
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, $sender_host_port is not defined for messages not received from a remote host.
-In the list below, '.' denotes standard messages with contents matching Exim's variable, '#' denotes standard variables with non-standard contents, and '+' denotes a non-standard variable.
+Internally, all variables are represented as strings, meaning any operator will work on any variable. This means that '$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.
