zimbra 8.6 spam mails on distribution list

[vignesh]

I have installed zimbra 8.6.
I am getting spams on only one distribution list and i am not able to stop it.
The incoming spam mails are from different domains.
Any help would be appreciated!

You really shouldn't start duplicate threads on what are, essentially, the same topic - do not keep doing this. Your other thread has details that say you've disabled anti-spam and anti-virus on your server (and apparently a nine month old problem) or am I imagining this, you need to fix that problem first. I also suggested you upgrade to the most recent version of ZCS as the one your using is old and no longer supported.

now all the outgoing mails i send from zimbra it gets differed. Not able to figure out what is the reason.
I have checked all MX , A records it is fine.
