Mail Exchange Server!

[Bernini]

Hi All

The company i'm working for has decided to move from Ms Exchange Server (finally!). The problem is that i have no idea of a similar product which can handle or work in the same manner.

The requirements are: (obviously)

- To send and receive mail from a fixed doamin name
- Monitoring
- Administration
- Spam filtering

What Open Source (even not) products are there available which can be used in this case?

Thanks
B

In *nix systems there is a philosophy that is diametric opposition to the Micro$oft way of things. That philosophy is write an application that does one thing and make it do it very well, them make it interoperate with other things that do their one thing very well.

In this case I use:
[ul]
[li]postfix to send and receive mail[/li]
[li]monitoring email? I don't, that's snooping, tantamount to wire-tapping, and could be against the law.[/li]
[li]web-cyradm to administrate the incoming mail and users.[/li]
[li]spamassassin for filtering.[/li]
[/ul]
Two things you don't mention:
[ul]
[li]Allowing users to read mail via pop or imap protocols (I use cyrus-imapd)[/li]
[li]Virus scanning (I don't have to because we don't use windows, but amavis-new or clamav are both very well liked)[/li]
[/ul]

I also provide my users with a web interface for their mail called squirrelmail.

I think you'd have to look to Notes, GroupWise, or OpenExchange Server to do what Exchange does. But, since you mention only e-mail, Eric is right. I use:

Postfix for mail delivery
Courier-IMAP for mail retrieval
Webmin for administration
Spamassassin for filtering
ClamAV for antivirus
Squirrelmal for webmail access

Note: no calendar, notes or other groupware features.

For a business, I'd recommend looking to something a little higher up the food chain for AV, perhaps Trend Micro. I used their product for Exchange with great success, and they have some Linux support.

For monitoring, you can check the logs pretty easily to track message counts, etc. If archiving is what you need, you'll need another program to do that. We used an external gateway server to write all inbound and outbound e-mail to a SQL database and WORM drives.

I have yet to put a shared calendar app into production, but I hear the mozilla sunbird project is coming along nicely. Squirrelmail has a nice shared calendar plugin available.

Not sure about the 'Exchange' portion of it all, but if you are looking into email, you can't have a thread without mentioning
