[rt-users] rt-mailgate not relpying to new tickets via email

[Gian Sartor]

Hello all,

We are running RT 3.4, having recently upgraded from 3.3, on Debian 
testing. I noticed yesterday that the auto response emails to newly 
created tickets are not being sent out. Tickets are ending up in the 
correct queues, with the correct requester name, and in the ticket 
history, RT has a note saying that the email has been sent. Admin CC's 
of the relevant queues are receiving emails to say that a new ticket has 
come in.

These lines appear in the log file:

Jun 13 15:11:13 server RT:

c:  (/usr/share/request-tracker3.4/lib/RT/Action/SendEmail.pm:297)

While searching for answers, the only thing I have found that relates to 
my problem is that I am missing the "-t" option from the script that 
reads the header. I assumed that this would be in rt-mailgate (but I am 
new to RT and am likely to be wrong) and it is not there.

Can anyone help / point me in the right direction?
