Same problem here, too. We just needed to do the contrary: deactivate AS and AV services.
The error message also triggers when saving any modification you commit when changing the MTA section (in my case, the trusted networks).
Alas, we're gonna go in production with the NE in about a month... :-(
Just tried
Code:
zmprov ms `zmhostname` +zimbraServiceDisabled antivirus
but didn't work...
I searched for zmprov ms syntax, but I found nothing. That's why I just "guessed" the disable version of your command, mmorse!
Thanks in advance, keep up the good work!
