Hello everyone!
I have a weird problem. My send mail that was working last week suddenly does not. I am not running the sendmail daemon just using smart relay.
If I set the sendmail.config file DS 192.168.5.33 then do a sendmail -v tim.ttksg.com, it comes back with the messages
tim@ttksg.com.... Connecting to 0.0.0.0. via relay
tim@ttksg.com.... Deffered: Connection refused by 0.0.0.0.
any idea what would be causing this?
Thanks!
Solved! Go to Solution.

Re: sendmail is trying to connect to 0.0.0.0 via relay
sendmail.cf is the likely culprit, followed by /etc/hosts, maybe DNS.
What does:
grep -e "0.0.0.0" -e ^DS /etc/mail/sendmail.cf
show? The DS directive defines the smart relay. 0.0.0.0 should only appear in comments.
If DS shows a hostname such as mail.bozo.com, what does:
nslookup mail.bozo.com
show? Also look at /etc/mail/sendmail.cw for errors.
To avoid DNS messing up your email, change the DS address to IP rather than hostname.

Re: sendmail is trying to connect to 0.0.0.0 via relay
Hi Bill,
DS192.168.5.33
I am confused... because I have 3 HP servers and they are all doing the same thing.

Re: sendmail is trying to connect to 0.0.0.0 via relay
I found that there was a conflict between the the domain name and what the DNS server was liking.
Some places had xxxx.com and others had xxxx.local. As I said, this was working up until last week Friday so what ever changed was outside the HP servers. But the HP server were not correct. so I went through all the configuration files on HP-UX and made sure that they were all correct and that seemed to solve the problem
