766 exipick - display messages from Exim queue based on a variety of criteria
770 exipick [--help|--version] | [-spool <spool>] [-and|-or] [-bp|-bpa|-bpc|-bpr|-bpra|-bpru|-bpu] [<criterion> [<criterion> ...]]
774 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.
782 The path to Exim's spool directory. In general usage you should set the $spool variable in the script to your site's main spool directory (and if exipick was installed from the Exim distribution, this is done by default), but this option is useful for alternate installs, or installs on NFS servers, etc.
786 A message will be displayed only if it matches all of the specified criteria. This is the default.
790 A message will be displayed if it matches any of the specified criteria.
794 By default criteria using the '=' operator are caseless. Specifying this option make them respect case.
796 =item The -bp* options all control how much information is displayed and in what manner. They all match the functionality of the options of the same name in Exim. Briefly:
798 =item -bp display the matching messages in 'mailq' format.
800 =item -bpa ... with generated addresses as well.
802 =item -bpc ... just show a count of messages.
804 =item -bpr ... do not sort.
806 =item -bpra ... with generated addresses, unsorted.
808 =item -bpru ... only undelivered addresses, unsorted.
810 =item -bpu ... only undelivered addresses.
812 Please see Exim's spec.txt for details on the format and information displayed with each option.
814 =item The following options are included for compatibility with the 'exiqgrep' utility:
816 =item -f <regexp> Same as '$sender_address = <regexp>'
818 =item -r <regexp> Same as '$recipients = <regexp>'
820 =item -y <seconds> Same as '$message_age < <seconds>'
822 =item -o <seconds> Same as '$message_age > <seconds>'
824 =item -z Same as '$deliver_freeze'
826 =item -x Same as '!$deliver_freeze'
828 =item -c Display count of matches only
830 =item -l Display in long format (default)
832 =item -i Display message IDs only
834 =item -b Display brief format only
836 Please see the 'exiqgrep' documentation for more details on the behaviour and output format produced by these options
840 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.
842 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.
844 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')
856 =head1 VARIABLE TYPES
858 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.
864 Variable of the numeric type can be of integer or float. Valid comparisons are <, <=, >, >=, ==, and !=.
866 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'.
870 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.
874 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.
876 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$' on the more complex end. This comparison is caseless by default, but see the --caseful option to change this.
878 Slightly more complex is the string comparison with the operators 'eq' and 'ne' for equal and not equal, respectively. '$sender_helo_name eq hotmail.com' is true for messages with the exact helo string "hotmail.com", while '$sender_helo_name ne hotmail.com' is true for any message with a helo string other than "hotmail.com".
880 The most complex and the most flexible format are straight regular expressions with the operators '=~' and '!~'. The value in the criteria is expected to be a correctly formatted perl regular expression B<including the regexp delimiters (usually //)>. The criterion '$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.
886 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.
888 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.
890 =head2 Boolean variables
894 =item + $allow_unqualified_recipient
896 TRUE if unqualified recipient addresses are permitted in header lines.
898 =item + $allow_unqualified_sender
900 TRUE if unqualified sender addresses are permitted in header lines.
902 =item + $deliver_freeze
904 TRUE if the message is currently frozen.
906 =item . $first_delivery
908 TRUE if the message has never been deferred.
910 =item . $manually_thawed
912 TRUE when the message has been manually thawed.
914 =item + $dont_deliver
916 TRUE if, under normal circumstances, Exim will not try to deliver the message.
918 =item . $host_lookup_deferred
920 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.
922 =item . $host_lookup_failed
924 TRUE if there was an attempt to look up the host's name from its IP address, but the attempt returned a negative result.
926 =item + $local_error_message
928 TRUE if the message is a locally-generated error message.
930 =item + $sender_local
932 TRUE if the message was locally generated.
934 =item + $sender_set_untrusted
936 TRUE if the envelope sender of this message was set by an untrusted local caller.
938 =item . $tls_certificate_verified
940 TRUE if a TLS certificate was verified when the message was received.
944 =head2 Numeric variables
948 =item . $body_linecount
950 The number of lines in the message's body.
952 =item . $body_zerocount
954 The number of binary zero bytes in the message's body.
956 =item + $deliver_frozen_at
958 The epoch time at which message was frozen.
960 =item . $interface_port
962 The local port number if network-originated messages.
966 The number of seconds since the message was received.
968 =item . $message_body_size
970 The size of the body in bytes.
972 =item . $message_size
974 The size of the message in bytes.
976 =item . $originator_gid
978 The group id under which the process that called Exim was running as when the message was received.
980 =item . $originator_uid
982 The user id under which the process that called Exim was running as when the message was received.
984 =item . $received_count
986 The number of Received: header lines in the message.
988 =item + $received_time
990 The epoch time at which the message was received.
992 =item . $recipients_count
994 The number of envelope recipients for the message.
996 =item + $recipients_del_count
998 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.
1000 =item + $recipients_undel_count
1002 The number of envelope recipients for the message which have not yet been delivered.
1004 =item . $sender_host_port
1006 The port number that was used on the remote host for network-originated messages.
1008 =item + $warning_count
1010 The number of delay warnings which have been sent for this message.
1014 =head2 String variables
1018 =item . $acl_c0-$acl_c9, $acl_m0-$acl_m9
1020 User definable variables.
1022 =item . $authenticated_id
1024 Optional saved information from authenticators, or the login name of the calling process for locally submitted messages.
1026 =item . $authenticated_sender
1028 The value of AUTH= param for smtp messages, or a generated value from the calling processes login and qualify domain for locally submitted messages.
1030 =item + $bmi_verdicts
1032 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).
1034 =item + $each_recipients
1036 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.
1038 =item + $each_recipients_del
1040 Like $each_recipients, but for the $recipients_del variable.
1042 =item + $each_recipients_undel
1044 Like $each_recipients, but for the $recipients_undel variable.
1048 The value of the same named message header, for example header_to or header_reply-to. These variables are really closer to Exim's rheader_* variables, with the exception that leading and trailing space is removed.
1050 =item . $interface_address
1052 The address of the local IP interface for network-originated messages.
1054 =item . $local_scan_data
1056 The text returned by the local_scan() function when a message is received.
1058 =item # $message_body
1060 The message's body. Unlike Exim's variable of the same name, this variable contains the entire message body. The logic behind this is that the message body is not read unless it is specifically referenced, so under normal circumstances it is not a penalty, but when you need the entire body you need the entire body. Like Exim's copy, newlines and nulls are replaced by spaces.
1062 =item . $message_headers
1064 A concatenation of all the header lines except for lines added by routers or transports.
1068 The unique message id that is used by Exim to identify the message.
1070 =item + $originator_login
1072 The login of the process which called Exim.
1074 =item . $received_protocol
1076 The name of the protocol by which the message was received.
1080 The list of envelope recipients for a message. Unlike Exim's version, this variable always contains every envelope recipient of the message. The recipients are separated by a comma and a space.
1082 =item + $recipients_del
1084 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.
1086 =item + $recipients_undel
1088 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.
1090 =item . $reply_address
1092 The contents of the Reply-To: header line if one exists and it is not empty, or otherwise the contents of the From: header line.
1094 =item . $sender_address
1096 The sender's address that was received in the message's envelope. For bounce messages, the value of this variable is the empty string.
1098 =item . $sender_address_domain
1100 The domain part of $sender_address.
1102 =item . $sender_address_local_part
1104 The local part of $sender_address.
1106 =item . $sender_helo_name
1108 The HELO or EHLO value supplied for smtp or bsmtp messages.
1110 =item . $sender_host_address
1112 The remote host's IP address.
1114 =item . $sender_host_authenticated
1116 The name of the authenticator driver which successfully authenticated the client from which the message was received.
1118 =item . $sender_host_name
1120 The remote host's name as obtained by looking up its IP address.
1122 =item . $sender_ident
1124 The identification received in response to an RFC 1413 request for remote messages, the login name of the user that called Exim for locally generated messages.
1126 =item . $smtp_active_hostname
1128 The value of the active host name when the message was received, as specified by the "smtp_active_hostname" option.
1132 The spam score of the message, for example '3.4' or '30.5'. (Requires exiscan or WITH_CONTENT_SCAN)
1134 =item . $spam_score_int
1136 The spam score of the message, multiplied by ten, as an integer value. For instance '34' or '305'. (Requires exiscan or WITH_CONTENT_SCAN)
1140 The cipher suite that was negotiated for encrypted SMTP connections.
1144 The value of the Distinguished Name of the certificate if Exim is configured to request one.
1152 =item exipick '$deliver_freeze'
1154 Display only frozen messages.
1156 =item exipick '$received_protocol eq asmtp' '$message_age < 20m'
1158 Display only messages which were delivered over an authenticated smtp session in the last 20 minutes.
1160 =item exipick -bpc '$message_size > 200K'
1162 Display a count of messages in the queue which are over 200 kilobytes in size.
1164 =item exipick -or '$sender_helo_name =~ /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/' '$sender_helo_name = _'
1166 Display message which have a HELO string which either is an IP address or contains an underscore.
1172 None that I know of, except an Exim installation. Your life will also be a lot easier if you set $spool at the top of the script to your install's spool directory (assuming this was not done automatically by the Exim install process).
1174 =head1 ACKNOWLEDGEMENTS
1176 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.
1178 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.
