Outgoing mail issue

[dljordaneku]

My server didn't really crash this morning but everything was moving so slow that I couldn't do anything so I had to force a shutdown on the system. After it came back up, no one in outside networks can send email. I ran a mailsrv:/etc/init.d # ps -aef | grep sasl
and got permission denied. I ran it as a zimbra user.

This is what I am getting from my zimbra.log

HI all,
You may have the local network to be trusted, thats why users from the local network are not enforced to be authenticated before delivering email.
And when users trying to mail from outside the network are enforced to authenticate their self.
Please start saslauthd server as root and then try.

All of this was working before the system decided to come to a halt Friday morning. I went in and made a change to the host file and on reboot Fedora said I had some file system errors so I ran a fsck on it and after that, it all started working fine again so who knows which fixed it if any.

saslauthd may have not been running after the reboot from the morning. All is well for now. Or at least enough until I can get back to work in a week and put upgrading to Fedora 10 and to the latest Zimbra.

Why was change in host file was required, and what was the change?

saslauth is to be started as zimbra user and not root. run zmsaslauthd start.

Hello,

I had the same issue after a fresh install of ZCS5.0 and a domain migration (manual). Seems that every now and again saslauth stops. as zimbra 'zmsaslauthdctl stop ; zmsaslauthdctl start' did the trick (for now!).

I'm curious to why is never started upon reboot of the server ...
