Re: Zimbra for Production environment recommendation

Virtual when possible. For the obvious advantages of virtualization: snapshot before upgrade, virtual disks, vm migration, etc..

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.

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.
