Disable SMTP and allow it only for few domains.
I have searched through the forums but still in need of some clarification for this subject:
how may I block the use of SMTP (by mobile and desktop mail clients) for all users except few domains?
I mean I have to allow only few domains to use zimbra auth smtp and leave others to own SMTP services...
As an alternative I would like to simply change SMTP port from 25/465/587 to some other value.
Thanks and regards!
