Problem with mailgate, REST, and some other stuff

I’m migrating RT from an openSUSE 10.1 virtual machine to a 10.3 virtual
machine. My process has been to simply build RT to an identical state
on the new VM and then merely copy a database dump from the old to the
new instance. This doesn’t want to work though.

Last night I encountered the following in the mail log:
Jun 4 11:39:52 rt postfix/local[25890]: 1DEAEB806A:
to=rt@rt.companyname.com, relay=local, delay=42308,
delays=42307/0.01/0/0.41, dsn=4.3.0, status=deferred (temporary failure.
Command output: An Error Occurred ================= 403 Forbidden )

I did a search online and found that someone else had a similar problem
which related to REST. Looking in the httpd log I find this:
127.0.0.1 - - [03/Jun/2008:23:14:46 -0400] “GET / HTTP/1.0” 403 1000 “-”
“Apache/2.2.4 (Linux/SUSE) (internal dummy connection)”
and
127.0.0.2 - - [03/Jun/2008:23:36:39 -0400] “POST
//REST/1.0/NoAuth/mail-gateway HTTP/1.1” 403 1058 “-” “libwww-perl/5.806”.

Searching online I found the following rt-users mailing list post from a
year and a half ago:
http://lists.bestpractical.com/pipermail/rt-users/2006-October/042251.html

The user mentions finding something in the wiki but doesn’t specify
what. However, my own searches came up empty for anything which looked
related.

Can someone help me troubleshoot this?

Thanks,
Mathew
