Are you serious?

Thanks! What do you mean?

Quote from Delta04

I strongly recommend so that mail function can be disabled from the Php-editor section for each domain (adding a "mail" button in the "Value for the disable_functions directive").

I encounter may websites with poor security that are spamming via php. The only option to stop them, as an server administrator without cutting the whole account, was to manualy edit the php setting by adding mail to disabled function. Unfortunately this is overwritten on the next update or by other reason.

Thanks!

Hi! How do you do it manually? I've the same problem.

Thank you Ninos,

mailq was full of emails from an hosted website that is now suspended. I purged those emails and I'm gonna monitor mailq to check if new spam messages will be queued. Is this correct? Otherwise I will contact you to check the situation.

For specific domain delete I've issued this command

postqueue -p | tail -n +2 | awk 'BEGIN { RS = "" } /@abcdefghdomain\.com/ { print $1 }' | tr -d '*!' | postsuper -d -

cat /var/log/mail.info | grep relay= | tail

Thanks Ninos, in fact I have a lot of deferred emails :s
I've tried to suspend all hosted websites but it seems that postifx is still "under attack"...

Thanks but what to look for?

I've got some more details...

Hi all! Recently one of my servers has been blacklisted by Spamhaus ZEN, CBL, ivmSIP. Do you have any suggestion about how to check the root cause? The installed i-MSCP version is 1.2.9.
Thank you!

Quote from Ninos

• Use the sitewide-bayes. See also the config file:
  https://github.com/i-MSCP/plug…amAssassin/config.php#L49
• you need to import/export the spamassassin-db
• therefore you need dovecot, the RoundcubePlugins plugin with activated manage-sieve and a first login per mail account into the roundcube webmailer. But it's easier just to reject spam mails
  https://github.com/i-MSCP/plug…amAssassin/config.php#L42

It seems that the reject spam mails options it's not working even after plugin deactivation/activation and SpamAssassin service restart.

Thank you very much!

Is it possible to apply a filter on email subject and/or body?

How to apply config.php changes? Is it enough to save file changes?

Hi! I'm using i-mscp 1.2.2 + roundcube + roundcube plugins + spamassassin and I'd like to know if it is possible to:

- apply a rejection filter for all i-mscp email accounts of a given domain (what I do now is setup a filter for each email account through roundcube settings :\ )
- import/export filter rules
- move automatically marked as spam emails to junk folder

Thanks!
