PROGRAM:

NAME

rt-mailgate - Mail gateway for Request Tracker

SYNOPSIS

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 ]

OPTIONS

"--action"
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".

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

"--url"
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.

"--no-verify-ssl"
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).

DESCRIPTION

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.

SETUP

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

bugs-comment: "|/usr/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.

CUSTOMIZATION

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 =>
"Filter::SpamAssassin",
"Auth::LDAP",
# ...
);

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.

WRITING PLUGINS

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:

Message
A "MIME::Entity" object representing the email

CurrentUser
An "RT::CurrentUser" object

AuthStat
The authentication level returned from the previous plugin.

Ticket [OPTIONAL]
The ticket under discussion

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

Action
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.

ENVIRONMENT

EXTENSION
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.
