Some requestors not getting correspondence

Hi All,

A small number of requestors are not getting email from RT. Usually the
requestors are from the same domain - eg bob@domain.net.nz or
peter@domain.net.nz and effects a couple of domains.

We have RT installed on a Redhat 8 box. The box sits behind a firewall on a
intranet using a public address. We us fetchmail to pull incoming emails
from a mail server in our DMZ. Email is sent directly through the firewall
from our RT box using sendmail.

I was thinking that maybe the mailserver on these domains is putting these
emails into a black hole thinking they are spam - we don’t get any ‘can not
deliver’ responses.

Below is an example of the the autogenerated reply that doesn’t get to
requestors. I though a couple of things might cause problems but not sure -
generic return-path, mydomain.co.nz isn’t a real domain (ie no reverse
lookup). I changed the Precedence to Normal but this doesn’t seem to make
any differenct.

Any help appreciated. Greg.

sounds plausible. I’d run tcpflow on the rt box, and see if you can
capture RT sending mail to them. Either you’ll be able to, in which
case there’s not much you can do to fix it, or there’ll be some more
serious problem with your rt setup.
