Can't email outside of our domain

RT Users
1

This isn’t directly related to RT, but I am hoping that someone can help.
We’ve recently noticed that RT’s emails are not making it to any email
addresses outside of our domain. Things work perfectly for employees, but as
soon as the requestor is a yahoo address (for example), they never get the
autoreply email.

Here is the relevant entry in our mail log. Can someone point me in the
right direction?

This is being relayed through exchange.

Thanks in advance

I’m really not any exchange- or sendmail-expert, but the domains
“hkusa.com” and “hkrt.hkusa.com” are different.
The former exists and has an MX-record, the later does not.
Some mailservers (including my very own) reject mails where the sender
has a clearly non-existing email-address (helo spam).

Perhaps you should create a MX entry for hkrt.hkusa.com and point it to
the same server as the MX for hkusa.com, using whatever techniques
MSFT-exchange provides to sort-out the mails…
Whatever MX you configure for hkrt, it should ideally also provide the
outgoing mail, as some servers reject mail that is not sent from the
MX…

Here is the relevant entry in our mail log. Can someone point me in the

since this is being relayed through exchange, you’ll have to look at
the exchange logs to see what’s going on.

However, I notice your rt seems to be sending mail as
“nobody@hkrt.hkusa.com” hkrt.hkusa.com does not have an MX or A record
I can see. This means several sites will bounce is as spam.

Any idea why it is coming as nobody? I can’t find that in any RT config
files…

Perhaps your web server runs as user nobody?

grep ^User /path/to/httpd.conf

If that is not it, then I don’t know.
