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 your RT server uses SSL, you will need to install additional Perl libraries. RT will
          detect and install these dependencies if you pass the "--enable-ssl-mailgate" flag to
          configure as documented in RT's README.

          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.

          Verifying SSL certificates requires LWP::UserAgent version 6.0 or higher; explicitly
          passing "--verify-ssl" on prior versions will error.

       "--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.
       However, you will need first of all to create an RT user for the mail gateway and assign
       it a password; this helps to ensure that mail coming into the web server did originate
       from the gateway.

       Next, 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.

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.
