NAME

exipick - selectively display messages from an Exim queue  

SYNOPSIS

exipick [<options>] [<criterion> [<criterion> ...]]  

DESCRIPTION

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.  

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'  

OPTIONS

--and
Display messages matching all criteria (default)
-b
Display messages in brief format (exiqgrep)
-bp
Display messages in standard mailq format (default)
-bpa
Same as -bp, show generated addresses also (exim)
-bpc
Show a count of matching messages (exim)
-bpr
Same as '-bp --unsorted' (exim)
-bpra

-z
Same as '$deliver_freeze' (exiqgrep)
 

CRITERIA

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.

See the VARIABLES and OPERATORS sections below for more details  

OPERATORS

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'
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 mulitplied by 86400, 3600, 60, 1, 1048576, 1024, or 1 respectively. Examples of valid numeric tests:
  '$message_age >= 3d'
  '$local_interface == 587'
  '$message_size < 30K'
STRING
The string operators are =, eq, ne, =~, and !~. With the exception of '=', the operators all match the functionality of the like-named perl operators. eq and ne match a string exactly. !~, =~, and = apply a perl regular expression to a string. The '=' operator behaves just like =~ but you are not required to place // around the regular expression. Examples of valid string tests:
  '$received_protocol eq esmtp'
  '$sender_address = example.com'
  '$each_recipients =~ /^a[a-z]{2,3}@example.com$/'
NEGATION
There are many ways to negate tests, each having a reason for existing. Many tests can be negated using native operators. For instance, >1 is the opposite of <=1 and eq and ne are opposites. In addition, each individual test can be negated by adding a ! at the beginning of the test. For instance, '!$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.
 

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 '$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

S . $acl_c0-$acl_c9, $acl_m0-$acl_m9
User definable variables.
B + $allow_unqualified_recipient
TRUE if unqualified recipient addresses are permitted in header lines.
B + $allow_unqualified_sender
TRUE if unqualified sender addresses are permitted in header lines.
S . $authenticated_id
Optional saved information from authenticators, or the login name of the calling process for locally submitted messages.
S . $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.
S . $bheader_*, $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.
S + $bmi_verdicts
The verdict string provided by a Brightmail content scan
N . $body_linecount
The number of lines in the message's body.
N . $body_zerocount
The number of binary zero bytes in the message's body.
S + $data_path
The path to the body file's location in the filesystem.
B + $deliver_freeze
TRUE if the message is currently frozen.
N + $deliver_frozen_at
The epoch time at which message was frozen.
B + $dont_deliver
TRUE if, under normal circumstances, Exim will not try to deliver the message.
S + $each_recipients
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.
S + $each_recipients_del
Like $each_recipients, but for $recipients_del
S + $each_recipients_undel
Like $each_recipients, but for $recipients_undel
B . $first_delivery
TRUE if the message has never been deferred.
S . $header_*, $h_*
This will always match the contents of the corresponding $bheader_* variable currently (the same behaviour Exim displays when iconv is not installed).
S + $header_path
The path to the header file's location in the filesystem.
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.
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.
B + $local_error_message
TRUE if the message is a locally-generated error message.
S . $local_scan_data
The text returned by the local_scan() function when a message is received.
B . $manually_thawed
TRUE when the message has been manually thawed.
N . $max_received_linelength
The number of bytes in the longest line that was received as part of the message, not counting line termination characters.
N . $message_age
The number of seconds since the message was received.
S # $message_body
The message's body. Unlike Exim's variable of the same name, this variable contains the entire message body. Newlines and nulls are replaced by spaces.
B + $message_body_missing
TRUE is a message's spool data file (-D file) is missing or unreadable.
N . $message_body_size
The size of the body in bytes.
S . $message_exim_id, $message_id
The unique message id that is used by Exim to identify the message. $message_id is deprecated as of Exim 4.53.
S . $message_headers
A concatenation of all the header lines except for lines added by routers or transports. RFC2047 decoding is performed
S . $message_headers_raw

N . $received_count
The number of Received: header lines in the message.
S . $received_protocol
The name of the protocol by which the message was received.
N . $received_time
The epoch time at which the message was received.
S # $recipients
The list of envelope recipients for a message. Unlike Exim's version, this variable always contains every recipient of the message. The recipients are separated by a comma and a space. See also $each_recipients.
N . $recipients_count
The number of envelope recipients for the message.
S + $recipients_del
The list of delivered envelope recipients for a message. This non-standard variable is in the same format as $recipients and contains the list of already-delivered recipients including any generated addresses. See also $each_recipients_del.
N + $recipients_del_count
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.
S + $recipients_undel
The list of undelivered envelope recipients for a message. This non-standard variable is in the same format as $recipients and contains the list of undelivered recipients. See also $each_recipients_undel.
