exipick [<options>] [<criterion> [<criterion> ...]]
exipick --help|--man
=head1 DESCRIPTION
B<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. B<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 CRITERIA
B<Exipick> decides which messages to display by applying a test against each message. The rules take the general form of "I<VARIABLE> I<OPERATOR> I<VALUE>". For example, C<< $message_age > 60 >>. When B<exipick> is deciding which messages to display, it checks the C<$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 C<--or> option is used, a message is displayed as long as any of the criteria evaluate to true.
See the VARIABLES and OPERATORS sections below for more details
=head1 OPERATORS
=over 4
=item BOOLEAN
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 NUMERIC
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
=item STRING
The string operators are =, eq, ne, =~, and !~. With the exception of C<< = >>, 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 C<< = >> 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
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, C<< !$acl_m1 =~ /^DENY$/ >> is the same as C<< $acl_m1 !~ /^DENY$/ >>. Finally, every test can be specified by using the command line argument C<--not>. This is functionally equivalent to adding a ! to the beginning of every test.
=back
=head1 VARIABLES
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.
Internally, all variables are represented as strings, meaning any operator will work on any variable. This means that C<< $sender_host_name > 4 >> is a legal criterion, even if it does not produce meaningful results. Variables in the list below are marked with a 'type' to help in choosing which types of operators make sense to use.
Identifiers
B - Boolean variables
S - String variables
N - Numeric variables
. - Standard variable matching Exim's content definition
# - Standard variable, contents differ from Exim's definition
+ - Non-standard variable
=over 4
=item S . B<$acl_c0>-B<$acl_c9>, B<$acl_m0>-B<$acl_m9>
User definable variables.
=item B + B<$allow_unqualified_recipient>
TRUE if unqualified recipient addresses are permitted in header lines.
=item B + B<$allow_unqualified_sender>
TRUE if unqualified sender addresses are permitted in header lines.
=item S . B<$authenticated_id>
Optional saved information from authenticators, or the login name of the calling process for locally submitted messages.
=item S . B<$authenticated_sender>
The value of AUTH= param for smtp messages, or a generated value from the calling processes login and qualify domain for locally submitted messages.
=item S . B<$bheader_*>, B<$bh_*>
Value of the header(s) with the same name with any RFC2047 words decoded if present. See section 11.5 of Exim's spec.txt for full details.
=item S + B<$bmi_verdicts>
The verdict string provided by a Brightmail content scan
=item N . B<$body_linecount>
The number of lines in the message's body.
=item N . B<$body_zerocount>
The number of binary zero bytes in the message's body.
=item S + B<$data_path>

=item S + B<$each_recipients>
This is a pseudo variable which allows you to apply a test against each address in $recipients individually. Whereas C<< $recipients =~ /@aol.com/ >> will match if any recipient address contains aol.com, C<< $each_recipients =~ /@aol.com$/ >> will only be true if every recipient matches that pattern. Note that this obeys C<--and> or C<--or> being set. Using it with C<--or> is very similar to just matching against $recipients, but with the added benefit of being able to use anchors at the beginning and end of each recipient address.
=item S + B<$each_recipients_del>
Like $each_recipients, but for $recipients_del
=item S + B<$each_recipients_undel>
Like $each_recipients, but for $recipients_undel
=item B . B<$first_delivery>
TRUE if the message has never been deferred.
=item S . B<$header_*>, B<$h_*>
This will always match the contents of the corresponding $bheader_* variable currently (the same behaviour Exim displays when iconv is not installed).
=item S + B<$header_path>
The path to the header file's location in the filesystem.
=item B . B<$host_lookup_deferred>
TRUE if there was an attempt to look up the host's name from its IP address, but an error occurred that during the attempt.
=item B . B<$host_lookup_failed>
TRUE if there was an attempt to look up the host's name from its IP address, but the attempt returned a negative result.
=item B + B<$local_error_message>
TRUE if the message is a locally-generated error message.
=item S . B<$local_scan_data>
