Should I use Majordomo? | What is Majordomo? | How to send commands to the mailing list manager | Basic commands
If you are a member of Essex University, then the preferred way of examining and altering your list membership is through the web interface. Only external users need use the majordomo commands.
Majordomo is a mailing list manager which automates the management of mailing lists.
The majority of mailing lists at Essex are now managed by Majordomo. Using Majordomo, it
is easy to manage your own membership of the various mailing lists at Essex. Commands to
the mailing list manager are sent to majordomo@majordomo.essex.ac.uk.
All emails to this address are processed by an email robot, which interprets various
commands sent to it. Replies from the robot are automatically generated, and sent back to
the sender of the original email message.
All messages to Majordomo should be emailed to majordomo@majordomo.essex.ac.uk. The email's Subject field should be left blank. Commands to Majordomo should be typed in the body of the message (i.e. in the main part of the new email message window). An example is shown in the image below:

This email is going to send the command which brettb, which will email back a list of the mailing lists to which the user brettb is subscribed. Note that the following line contains a single word - end. This line is essential if you have a signature automatically added to the end of your email messages, as it informs Majordomo that anything after the end word can be ignored.
After this email has been sent, it takes approximately 60 seconds for Majordomo to reply to the message. The email reply from the command which brettb is shown below:

This shows that the user brettb is a member of five mailing lists: helpdesk, pc-comment, webgroup, windows-people and word-for-windows-people.
It is possible to send multiple commands to Majordomo in a single email
message. To do this, put each command on a separate line. Majordomo will then process each
line of the email as a separate command, then stop when it reaches line with the end
command.
As has been shown previously, the command which username causes Majordomo to respond with a message containing a list of mailing lists to which the user is subscribed to. Majordomo has a large number of other commands which you may find useful. All of these commands are used in the same way as the which command.
