[rt-users] Rt4 MailgateInstallation: Stubborn 403 Forbidden Error

[Traiano Welcome]

Hi List

I've installed RT4 via the Debian package management system using the
following Wikia guide:
http://requesttracker.wikia.com/wiki/PostfixConfig ,  and operations
via the web interface seem  to be working fine. I am using
"apache2-modperl2.conf".

However, I am having an issue trying to get MailGate to work so that I
can log tickets via email. Most notably, my attempts to log tickets
via email fail with the following errors:

>From the Postfix logs:

----

failure. Command output: An Error Occurred =================  403
Forbidden )

----

I have reviewed and tested the solution on these 2 threads, without success:

1. http://lists.bestpractical.com/pipermail/rt-users/2009-April/058768.html
2. http://www.mentby.com/Group/rt-users/maillog-403-forbidden.html

Other than this I cannot find any other solutions on the internet
based on similar experiences from other users of RT4.

My questions are:

a) Is this a known issue with a known fix? If so, I'd appreciate a
pointer to it?
b) If not, is there some approach I could use to debugging this in
more detail so that I can pinpoint exactly what should be changed to
allow rt-mailgate to post messages to the REST API for Rt4 ?

Below are elements of my configuration for RT, mail and Apache:

I am using the following Apache configuration:

My /etc/aliases configuration looks like this:

---
test: "|/usr/bin/rt-mailgate --queue test --action correspond --url
http://centcomm.engeneon.net/rt"
test-comment: "|/usr/bin/rt-mailgate --queue testt --action comment
--url http://centcomm.engeneon.net/rt
---

A manual test of the rt-mailgate script produces the following:

---
root at centcomm:~# cat testfile.txt |/usr/bin/rt-mailgate --queue
support --action correspond --url http://centcomm.engeneon.net/rt
An Error Occurred

My apache2-modperl2.conf looks like this:

---
