How do I disable Mailman ?
I don't use mailing list but Mailman seems to run 6 times simultaneously when I SSH and do 'top'.
Now I did
/etc/init.d/mailman stop
..and I gained 50Mb RAM on my modest 296Mb VPS with 6 domains. But I am a bit scared it will be back when booting. How do I disable it for good?
And for the VPS experts please, do you see any other unnecessary RAM eaters in my momentary TOP list:

You can modify services by going into Webmin -> Services -> Bootup and Shutdown. You can stop the service from there, as well as prevent it from starting up the next time your server boots.
You'll also want to disable the Mailman feature in Virtualmin by going into Virtualmin -> System Settings -> Features and Plugins, and unchecking the Mailman option. That'll prevent mailman from showing up as a feature in the individual Virtual Servers.
Also, another RAM saving measure would be to go into Email Messages -> Spam and Virus Scanning, and set "SpamAssassin client program" to "spamassassin (standalone program)".
It looks like you're running spamd in daemon mode now. And while that's overall a more efficient way of running it, it's a lot more RAM intensive to run the daemon. Moving to the standalone program will spare a decent amount of RAM at the expense of requiring more CPU, as it launches spamassassin each time an email comes in.

Thanks for the reply! Found the mailman link. It's actually here:
Webmin -> System -> Bootup and Shutdown
My Spam setting is already "spamassassin (standalone program)". I am not sure where the spamd comes from, I didn't noticed that before. But I noticed that my SPAM problem was a bit less the last few days.
So how can I switch spamd 'off' - or 'on' again if I want it back later?
Suddenly I get very high memory use with this process:
16365 nobody 22 0 86056 81m 356 S 0 28.4 0:00.00 clamd.virtualmi
I have still no idea how to disable SPAMD completely.

For ClamAV -- unfortunately, Clam (and SpamAssassin, for that matter) both can use a lot of CPU and Memory resources.
It's not abnormal for it's memory use to increase over time.
If you're low on memory, one option would be to restart the daemon each night.
Another option is that, like SpamAssassin, you can choose to run it without the daemon. That requires more CPU, but less RAM if you aren't receiving much email.
