mail server

[Muhammad Yousuf Khan <sirtcp@gmail.com>]

need suggestions, i know there are few populer mail servers like
postfix, sandmail etc out there.

here is some details about my office.

1. 20 users.
2. pop from main server
3. send via SMTP
4. local mail distribution IMAP

i am not looking in to easy or hard mail server. what i am looking is
it should be good for my carrier and  for my office too.
secure, stable, web base console etc.

btw, i have heard that there is a mailserver called zimbra. but i
think debian is not natively supporting it.

any help would be appreciable.



Thanks,
