rt-mailgate - Mail interface to RT.


    rt-mailgate --help : this text

Usual invocation (from MTA):

    rt-mailgate --action (correspond|comment|...) --queue queuename
                --url http://your.rt.server/
                [ --debug ]
                [ --extension (queue|action|ticket) ]
                [ --timeout seconds ]



Specifies what happens to email sent to this alias. The avaliable basic actions are: correspond, comment.

If you've set the RT configuration variable UnsafeEmailCommands, take and resolve are also available. You can execute two or more actions on a single message using a - separated list. RT will execute the actions in the listed order. For example you can use take-comment, correspond-resolve or take-comment-resolve as actions.

Note that take and resolve actions ignore message text if used alone. Include a comment or correspond action if you want RT to record the incoming message.

The default action is correspond.


This flag determines which queue this alias should create a ticket in if no ticket identifier is found.


This flag tells the mail gateway where it can find your RT server. You should probably use the same URL that users use to log into RT.

If you have a self-signed SSL certificate, you may also need to pass --ca-file or --no-verify-ssl, below.

--ca-file path

Specifies the path to the public SSL certificate for the certificate authority that should be used to verify the website's SSL certificate. If your webserver uses a self-signed certificate, you should preferentially use this option over --no-verify-ssl, as it will ensure that the self-signed certificate that the mailgate is seeing the right self-signed certificate.


This flag tells the mail gateway to trust all SSL certificates, regardless of if their hostname matches the certificate, and regardless of CA. This is required if you have a self-signed certificate, or some other certificate which is not traceable back to an certificate your system ultimitely trusts.

--extension OPTIONAL

Some MTAs will route mail sent to user-foo@host or user+foo@host to user@host and present "foo" in the environment variable $EXTENSION. By specifying the value "queue" for this parameter, the queue this message should be submitted to will be set to the value of $EXTENSION. By specifying "ticket", $EXTENSION will be interpreted as the id of the ticket this message is related to. "action" will allow the user to specify either "comment" or "correspond" in the address extension.

--debug OPTIONAL

Print debugging output to standard error

--timeout OPTIONAL

Configure the timeout for posting the message to the web server. The default timeout is 3 minutes (180 seconds).


The RT mail gateway is the primary mechanism for communicating with RT via email. This program simply directs the email to the RT web server, which handles filing correspondence and sending out any required mail. It is designed to be run as part of the mail delivery process, either called directly by the MTA or procmail, or in a .forward or equivalent.


Much of the set up of the mail gateway depends on your MTA and mail routing configuration.

You need to route mail to rt-mailgate for the queues you're monitoring. For instance, if you're using /etc/aliases and you have a "bugs" queue, you will want something like this:

    bugs:         "|/opt/rt4/bin/rt-mailgate --queue bugs --action correspond
              --url http://rt.mycorp.com/"

    bugs-comment: "|/opt/rt4/bin/rt-mailgate --queue bugs --action comment
              --url http://rt.mycorp.com/"

Note that you don't have to run your RT server on your mail server, as the mail gateway will happily relay to a different machine.


By default, the mail gateway will accept mail from anyone. However, there are situations in which you will want to authenticate users before allowing them to communicate with the system. You can do this via a plug-in mechanism in the RT configuration.

You can set the array @MailPlugins to be a list of plugins. The default plugin, if this is not given, is Auth::MailFrom - that is, authentication of the person is done based on the From header of the email. If you have additional filters or authentication mechanisms, you can list them here and they will be called in order:

    Set( @MailPlugins =>
        # ...

See the documentation for any additional plugins you have.

You may also put Perl subroutines into the @MailPlugins array, if they behave as described below.


What's actually going on in the above is that @MailPlugins is a list of Perl modules; RT prepends RT::Interface::Email:: to the name, to form a package name, and then use's this module. The module is expected to provide a GetCurrentUser subroutine, which takes a hash of several parameters:


A MIME::Entity object representing the email


An RT::CurrentUser object


The authentication level returned from the previous plugin.


The ticket under discussion


If we don't already have a ticket id, we need to know which queue we're talking about


The action being performed. At the moment, it's one of "comment" or "correspond"

It returns two values, the new RT::CurrentUser object, and the new authentication level. The authentication level can be zero, not allowed to communicate with RT at all, (a "permission denied" error is mailed to the correspondent) or one, which is the normal mode of operation. Additionally, if -1 is returned, then the processing of the plug-ins stops immediately and the message is ignored.



Some MTAs will route mail sent to user-foo@host or user+foo@host to user@host and present "foo" in the environment variable EXTENSION. Mailgate adds value of this variable to message in the X-RT-Mail-Extension field of the message header.

See also --extension option. Note that value of the environment variable is always added to the message header when it's not empty even if --extension option is not provided.
