ClamAV can be a memory hog at the best of times. If your mail server is feeling the pinch then there is a useful article in iRedMail’s own documentation on disabling it:
However, I have found that whilst the steps work, they don’t go quite far enough. The problem is that although the changes stop iRedMail from scanning mails for viruses, they leave ClamAV running in the background.
This means it can still eat up excessive amounts of memory getting ready to do, well nothing!
Completely Disable ClamAV
Just one extra step can completely stop the unwanted service and free up all that precious memory:
sudo update-rc.d clamav-daemon disable sudo update-rc.d clamav-freshclam disable
Thanks for reading, only a short article but I spent a lot of time working it out so hope it’s useful to some people!
