best email server?
I am sure this question has been asked a million times on this forum but like all the others im a newbie to linux. I wanted to setup an email server on my suse 9.1 box. Now i am looking for something really powerful, something that large corporations would use. I really don't care if it is a pain to setup, im ready to for it. I want opinions from all the linux gurus here. :wink:
I really like postfix, check it out http://www.postfix.org/
Well i recommend u to go for either Qmail or Sendmail.
these two mail server are really powerful and now a days in use
for Qmail...check out..
Trust me disable sendmail and use Postfix. It is fast powerful and can handle large volumes of mail.
Our company uses an exim4 cluster to handle over 1 million pop3 mailboxes.
Use Qmail !! best security !! they even have a reward to anyone who can find a security loophole in qmail.
I always used to use sendmail but moved to postfix a couple of years ago.
I would recommend qmail or postfix for small to large size systems and as Jason says, Exim for massive systems.
I use Exim on my server that handles my familys emails about 5 accounts works fine and you can use spamassassin and clam as plugins.
If you are looking for something robust, and a great system, use postfix. I have seen multiple postfix threads tearing up the CPU/RAM/Disk on a Dell 6650 spitting out about 1.5million emails an hour. Sendmail is not designed for that kind of locking and message handling. I have seen sendmail choke at 24000 messages an hour, just due to its horrible use of disk access.
If you are looking at a good, stable, simple-powerful system, qmail is the way to go. It is a bit better than postfix at handling a large amount of incoming mail on an already-busy server.
Let us know what you decided on.
