Trying to set up a mail server under CentOS7 - having done this with
CentOS5 and CentOS6 over the last decade with no issues and reliable
service, it was time to upgrade (?) to CentOS7. Shouldn't be a problem,
right?
Getting to grips with systemd has been challenging - to say the least.
So a brief overview of what I am trying to set up:
postfix / amavisd-new / spamassassin / clamav so we can receive mail and
deal with the major rubbish that gets thrown at any open port 25 smtp
service.
no problems installing each of the above and their configuration files.
Just as an aside, there are many recipes for this combo of packages -
none of which work as advertised. There was a time when one could safely
follow a how-to guide and have things working - I have regularly used
the CentOS wiki guides - however they have become stale and what worked
fine for 5 & 6 DO NOT WORK for CentOS7 - mainly due to systemd and firewalld
So we have:
systemctl status postfix.service
● postfix.service - Postfix Mail Transport Agent

but for the life of me, I cannot get clamd@amavisd to stay up.
It always comes up and then dies after about 1 second :
systemctl status clamd@amavisd.service
● clamd@amavisd.service - clamd scanner (amavisd) daemon

I can run the clamd service manually just fine and everything works - i.e.
/usr/sbin/clamd -c /etc/clamd.d/amavisd.conf –nofork=yes
returns a functioning service - thus my config files must be okay
but try it with systemd and you hit a brick wall - nothing in any logs
to give me a clue why it comes up and then closes down
After many days of google chasing,
I have found a number of folk hitting the same issue, yet none of these
have posted anything resembling a solution, most have had other issues
that were in error.
If there is anyone that has this combo of services working under CentOS7
and can shed any insight on why I cannot get this service to actually
run, it would be very much appreciated.
TIA
Rob
