Description

This PHP script shows the content of the mail queues of multiple servers and give you the possibility to hold, release, delete and reqeue single messages.

If you install a tiny wrapper script on mail servers, you may even remove or requeue multiple messages from a certain sender.

In addition, you can also requeue all messages (sendmail -q).

- Key-based SSH access to mail servers for webserver user

Installation

Unpack the archive beneath a webserver document root

Adapt the variables $mailservers and $user to your needs, if you like to use the selection by sender e-mail address feature, configure also variable $wrapper_cmd

Add the following lines to /etc/sudoers on the mail server(s), assuming user admin for login to the mail server(s) (change it to your needs):

admin    ALL=(ALL) NOPASSWD: /usr/sbin/postsuper
admin    ALL=(ALL) NOPASSWD: /usr/sbin/postqueue
admin    ALL=(ALL) NOPASSWD: /usr/local/bin/mailqueue.sh

(last line only needed for selection by sender address)

If you want to use the selection by e-mail address feature, put mailqueue.sh to some path on the mail server(s) and make it executable, e.g.:

cp mailqueue.sh /usr/local/bin/mailqueue.sh
chmod 755 /usr/local/bin/mailqueue.sh
