Help With SPAM
Currently I have installed Zimbra 8.0.5 on Redhat 6, I'm having spam attack, are using local accounts and somehow obtained the credentials of some users, and it is generating an amount of SPAM that I have listed in many RBL.
I wonder how to put more solid the antispam check if it is a SPAM even if the account is local.
Thank any suggestion.
If the spam is being sent by a local account then it's better security you need not changes to the anti-spam system, you should implement strong password immediately. Search the forums (and wiki) for details on how to improve the anti-spam system and also details on "compromised account".
