[rt-users] How does rt-mailgate work?

[Support]

Hi all,

On debian woody we have managed to get fetchmail to pop our support
account and believe it is passing e-mails to the rt-mailgate script.
But alas the tickets are not being created in RT.


Our .fetchmailrc config file in /root looks like this:

poll pop.clear.net.nz
        proto pop3
        user "support"
        pass "password"
        keep
        mda "/usr/bin/rt-mailgate --queue general --action correspond
--url http://path.to/rt/"

What does the rt-mailgate script do?  
How does it get the contents of the email (from, to, subject and body)
into a ticket in the correct format?
Does the rt-mailgate script connect directly to mysql to add data to the
ticket table or does it do it via http?

Best Regards
Dave
