[rt-users] RT email EX_TEMPFAIL looping problem

[Venkateswaran, Subbaraman]

Platform/Env:
RT 3.6.4, MySQL 5.1.34, Linux 2.6.9-42.ELsmp

Problem:
We are experiencing sporadic email looping problem. From the mail relay
server, emails bound for RT are aliased and piped to rt-mailgate and
recorded as correspondence into certain queues. For some emails,
rt-mailgate gets a return code EX_TEMPFAIL and the mail server does not
remove the email from its queue. This results in repetitive posting and
email flooding and finally we have to delete this email from the queue
to stop multiple posting.

Mail server aliases entry:
rt: "| path-to/rt-mailgate --url http://rt-server.com --queue general
--action correspond"

Even though rt-mailgate gets a return code EX_TEMPFAIL, the email seems
to have recorded fine in RT and we could see the ticket and attachments
created fine in RT.  

Please help us out with this problem and we are trying to understand if
this is any data inconsistency problem in RT or something else?

Some log entries from the RT server during this email looping. These
logs maynot be relevant to the problem, but I would like to present it
anyway if it might be helpful.
