Urgent: Sendmail / php mail not working for local files

Hello.

This morning exim didn't seem to be working on my server, and I found lots of this sort of message in the system messages log:

Apr 2 09:04:01 snoop named[56625]: client 212.50.33.5#31651: error sending response: not enough free resources

I restarted the box, all seemed fine.

But now any php mail scripts can't send mail to any local domains (contact forms - etc) with this in system messages:

Apr 2 15:44:40 servername sm-mta[69504]: m324idRR069502: SYSERR(root): mail.domain.com.au. config error: mail loops back to me (MX problem?)

Click to expand...

have checked that my /etc/virtual/domains file is still intact – which it is.

If I understand correctly it is that sendmail doesn’t know the domain is local, and once it looks up the MX record for the domain it sees it point to itself and then fails.

Can anybody point me in a direction of what to look at?

What sendmail version are you running?

Is the server's hostname in /etc/mail/local-host-names ?

Turns out that sendmail should not have been running at all, everything, including implementing the php mail() function, is done by Exim in DA.

Why, after two years, my latest reboot decided to start both Exim & Sendmail - I do not know?!?

Remove sendmail.
