Re: Account compromised impossibile to stop spam

Go for steps:
- Disable authentication at MTA level, then restart MTA service.
- Restrict zimbraMtaMynetworks to the mailserver only.

It can't spam this way, if keeps spamming it wil come from the machine itself.

or a malicious wordpress plugin installed on your 446.it website?
Have you explicitly set the website ip address into zimbraMtaMynetworks?

Re: Enforcing a match between FROM address and sasl username

The first method sets a rule that refuses the connection if the sasl_username used to authenticate on your MTA differs from the MAIL FROM: line of the envelope. Basically if someone steals your credentials, can authenticate as you@yourdomain.com, and then send a lot oof spam to internal accounts as ...

Re: Zimbra webmail SLOW

IOwait is around 10% constantly.
there's a high probability that you have a disk issue. That means slow working mysql and mailboxd. That means general poor performances.

Re: command databases mysql for multiserver

Re: Zimbra 8.8.9 and Cbpolicyd

About the first issue, is an old problem between zimbra and policyd. I think it's caused by the double postfix pass (postfix-> amavis-> postfix). I've tested that in systems without the amavis module, it works correctly. For what concerns the second issue, in 8.7.11 looks working fine: ... track=SAS...
