Re: Block SPAM email from new domains?

Hello,
By default Zimbra (8.8.9) seems to auto white-list mail that passes a DKIM test so no other spamassassin rules are applied (where is this - can I remove it easily ?)

What are the elements which make you thinking that ?

Regards,

Re: Server is hacked??

Hello,

it looks like you have been brute forced. In this case not only SMTP authentification could have been targeted, so
you must look in the /opt/zimbra/log/audit.log to see if there are some trails.
You can use fail2ban to stop this kind of attack.
