Sendmail stops working

[msp]

Hi there,

After a couple of weeks of not receiving any emails sent from a web-based contact form ("doh!"), sendmail appears to have stopped working.

From the mail log:
(!)ClamAV-clamd: Can't connect to UNIX socket /var/run/clamav/clamd.ctl: Connection refused, retrying (2)

Restarting ClamAV fixes the issue:

/etc/init.d/amavis restart

... However I'd like to find out what's causing this, as it has happened a number of times over the last 6 months.

Is the below related?

• Under ISPConfig admin interface > Monitor, I get: Your virus protection is OUTDATED!

• My ClamAV log (as shown in ISPConfig) is empty

• My FreshClam shows:

Is there something I should be doing?

Please help!

If you're using ISPConfig 3, you should have Postfix installed instead of Sendmail. What's in your mail log?

[msp]

Hey Falko, thanks for the response.

You are right, I didn't mean Sendmail.

I included the pertinent line from my mail log above, but here it is again:

(!)ClamAV-clamd: Can't connect to UNIX socket /var/run/clamav/clamd.ctl: Connection refused, retrying (2)

Would you mind weighing-in again?

Thanks!

Mat

Does /var/run/clamav/clamd.ctl exist? You can check with

ls -la /var/run/clamav/clamd.ctl

If not, does it exist after

/etc/init.d/amavis restart

?

[msp]

Hi, yes /var/run/clamav/clamd.ctl does exist.

At the moment mail is sending okay, it's just that it periodically stops. This could be every few months even. The problem is that I don't know of any way of monitoring it.

The problem is that if messages don't send, I don't get business enquiries, which is my primary income

You can use "monit" to monitor the process.

[msp]

I've installed monit, and looked through its documentation, but my one issue is this:

It appears monit uses the local mailserver to send email in the event of a problem.

The thing I need to monitor is the local mailserver itself, as that's the thing that is failing!

So I don't think using monit will work.

Can anyone help me? Why do I need to periodically manually restart clamav to make mail send?!

But you can at least use monit to restart the mail server if it fails.
