Hello,
Can anyone help me to find Mail server for Linux, and equal to MS Exchange, and with good performance.

?
There is no "best" car, "best" girl or "best" mail server. You ought to specify your needs first. (like how many users, what features ..., hardware ...)

"Best" is always subjective.

Many people have run Sendmail for years and love it.

These days a lost of people suggest Postfix and it is the default you get with RHEL6 though Sendmail is still available.

evolution provides calendar integration.

I have a IBM rack server with 4GB RAM, and 250GB HDD only, on this I want a Mail server which could be support no. of users, Which should be preferred after MS exchange?

Do you know anyone of them (evolution, sendmail or postfix or any other one)? Just try them and you will see what do you prefer. Noone of them will work exactly as an exchange server.
Or google:

I thought Evolution was just a mail client for individuals. I've not used Evolution myself so could be completely wrong but the discussion at this site seems to confirm my impression:
https://projects.gnome.org/evolution/arch.shtml

The user is asking about a mail server to manage mail transport(i.e. an MTA).

This Wikipedia describes what an MTA does and gives a list of various ones (including Postfix and Sendmail) near the bottom.
http://en.wikipedia.org/wiki/Message_transfer_agent

If you do a web search for something like "setting up enterprise mail using postfix" (or using sendmail or using ...) you'll get various hits.

Better yet would be to go a bit more generic to see other things you might want (such as a spam filter like spamassasain or a virus scanner like clamav). One such link would be:

Note that link shows Ubuntu and Postfix but it doesn't have to be either - it is just an example of what could be done.

I've yet to find a "replacement" for Exchange if your users are used to it.

Exchange when coupled with the web client or Outlook provides a nicely integrated e-mail/calendar/task/notes/contacts environment that pretty much has to be built from different linux equivalents.

Decide on your requirement, it may be that Exchange is actually your best option (I'm now ducking the inevitable flame-war from linux/open-source die-hards!)

I was recently the techincal lead on a project to examine our office mail/calendar/contacts options, we evaluated several options and our criteria was ease of "access anywhere" and on multiple mobile devices, so we actually ended up out-sourcing to Google Apps.

One possibility is Zimbra - http://www.zimbra.com/

I've used it in the past and loved it

. . . so True

Hi Guys and anandnenwani

I've seen a lot of Exim servers in my time. Cant say that I had any issues with them. worked quite well. Not sure if anyone else could say the same.

Since the users don't use "Exchange" the comments about ease of use are a bit off. Environments that have Exchange "servers" typically have "Outlook" clients. Or they use the web interface and bypass a locally installed client altogether.

Don't confuse client with server. You can often pick and choose which you use. (At a prior job we had Lotus Notes server and choice of clients - many of us used Eudora at the time as the client.)

Try zimbra.
