- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx): Nginx
- Manage mail accounts with iRedAdmin-Pro? yes
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.

Hi,
what's the difference between these logfiles:
/var/log/maillog
/var/log/mail.log

what's the best place to check if all processes are running? I have problems from time to time, that the server is running, users can connect fine, but no mail is delivered. Sometimes APD not running is the cause, sometimes it's ClamAV. Could it be another problem, too?

Usually I would use Puppet to check and keep important processes running, but because of the easy Setup I refrained from doing so on the iredmail machine. Should I? Is there an ansible alternative already available for this?

Thanks, best
Jochen

Run "ls -l /var/log/mail*".
On Debian/Ubuntu, "maillog" is a symbol link of "mail.log".

There's no such "place". You have to check log files.

How much memory does this server have? Is it always busy and high traffic?

It's ok to check process status and restart them.

it has 4 gb and is usually ideling away. 3/4 of mem used, no swap and plenty of core percentage available. But there are times where it is busy, usually because of some sort of attack, either to ssh or SPAM.

Ok, I will give this a try and install local Puppet and setup a cron job

thanks
