Hi Dear Support Team,
Can you please confirm if I need completely disable (just for temporary purpose) SpamAssassin, that's all what I need to do?

comment out this line in postfix main.cf to disable Amavisd + ClamAV + SpamAssassin:
#content_filter = smtp-amavis:[127.0.0.1]:10024

Should I do smth else after that? Restart services, server, etc...
I am facing some issues with delivering mail to my server from other domains, but I don't see any message in log, I get this information from users only, so just in case I decided to disable SpamAssassin.
Thanks.
