I am having a strange problem with my zimbra server. First, I notice a low performance of the webInterface, then I couldn start postfix service as usually. But the surprise was when I watched the mail queues: I have more than 250000 spam mails in the incoming queue,20000 in active and 53 in deferred!! Watching the senders/recipients domain I see that they're foreing domains, that's to say, the destination and origin of these mails are not my Zimbra-accounts.
I have installed several OS Zimbra but this is the first time I have this trouble. I dont know if its related with the AntiSpam or AntiVirus, becuase when I started ClamAV service it tried to connect to some url to update but there were no success.
Any idea what is happening? Thanks
