I currently have Virtualmin 1.5 running on CentOS 5.4, configured for postfix. Spamd is in fact running, and mailbox_command is set to “mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME”, but I do not see spamd in /var/log/maillog or anywhere else. Spam & virus scanning is enabled, but it doesn’t look like it is tagging any messages as spam, even on a gtube test.
Howdy,
If you look at the headers of the email, are you seeing any X-Spam-* headers in there?
Also, there’s a few places where Spam Processing would need to be enabled.
You’d need that setup in System Settings -> Features and Plugins, for one.
In Edit Virtual Server -> Enabled features, you can verify that it’s enabled for that particular Virtual Server.
And also, in Server Configuration -> Spam and Virus Delivery, you can tweak various settings related to spam processing.

Thanks for your help, but it’s enabled in all three places.
…and no, there are no X-SPAM flags in the header of any emails.
Okay.
Just for fun, what happens if you restart SpamAssassin (/etc/init.d/spamassassin restart)?
Do you see any errors in /var/log/maillog?
Now go ahead and send yourself an email – do you see errors regarding SA timeouts, or other problems?
-Eric
No errors in the logs. Spamassassin just restarts as normal during a restart – no errors.
I actually did notice a setting under Email Messages > Spam and Virus Scanning
I changed spamc to spamassassin, and now it works! What are the benefits/disadvantages to this, and why isn’t it working when set to spamc?
Thanks for your help!
Why isn’t it working with spamc? ATM, I have no idea 
However, using SpamAssassin (standalone) means that SA runs as a daemon, rather than spawning an entire new SA process each time an email comes in. It’s remarkably more efficient, at a cost of a little more RAM.
I’d personally recommend that on any setup where RAM isn’t significantly constrained.
-Eric
Ok, great. I’m not too much in need of ram, so I would probably even prefer the standalone over spamc.
Thanks for your help – I’ll try to diagnose the spamc issue if I ever decide to move back, but for now I think the standalone version will work better.
Yeah, using the standalong SA server is one of the first things I enable on any server I setup – I think that’s a good option since you have some available RAM.
But yeah, if you do figure out the spamc issue, by all means let us know, as that should work You might also take a peek in the /var/log/procmail.log file, perhaps some errors are showing up in there.
-Eric
This fixed my issue, Thanks
Info:
This was on a fresh install of Virtualmin Pro on Centos 7 for migration from Centos 6.6. The migration has been slow going.
I was pulling my hair out searching google until I searched with the correct phrase which was;
virtualmin spamassassin not working
Second result was; spamassassin running but not tagging … - Virtualmin
I’m glad to know that given enough ram, it’s the best option.
