Hi Folks,

As a security practice I would like to remove the default Postfix banner which I get when I telnet to zimbra on port 25. In a Postfix I know its pretty easy and just matter of changing one line in main.cf. How can that be configured in zimbra? I did check main.cf in /opt/zimbra but some how that setting is not being picked up system and it Postfix consistently appears.

220 zim.int.com ESMTP Postfix
