postcat - Displaying the contents of messages in the mail queues

The postcat program enables the administrator to have the contents of individual messages (e-mails in the mail queues) displayed in a readable format.

[/opt/MAIL/postfix/sbin/]postcat

[-vq] [-c <config_dir>] [<file> ... ]

-v

Activates detailed logging for debugging purposes.

-q

In this case you only need to specify the queue ID of the e-mail to be displayed as <file>. postcat then automatically determines the complete path name, i.e. the mail queue which contains <file>.

-c <config_dir>

The Postfix configuration file main.cf is located in the <config_dir> directory instead of the standard configuration directory.

<file> ...

Name(s) of the file(s)/e-mails whose contents are to be displayed:

• If you specify the -q option you need only specify the queue ID(s) of the message(s) to be output.

• If you do not specify the -q option, you must specify the complete path name(s) of the message(s).

Example

An e-mail with the queue ID 457106EA05 is contained in the deferred queue /var/spool/postfix/deferred/4/. A file with the name /var/spool/postfix/deferred/4/457106EA05 thus exists.

You can have the contents of the e-mail 457106EA05 displayed as follows:

• postcat /var/spool/postfix/deferred/4/457106EA05

  Here you must specify the complete path name as the argument.

• postcat -q 457106EA05

  With the -q option it is sufficient if you specify the queue ID of the e-mail to be displayed.
