Question local linux webmail and exchange 5.5


Hello everybody. I am looking for a mail solution for my facility. I am looking for something that the employees can access their email through Internet Explorer. Here is the thing, We are on a tight budget and I dont think they want to invest the money into exchange licensing. Is there a solution that I can use that runs off the *nix environment that could interface with my exchange 5.5? All info is appreciated. Thanks!

if you only need a simple webmail solution, have a look at imp or squirrelmail. Enable IMAP access on your Exchange server and let imp or squirrelmail access the exchange server as a client.

it's a pretty simple setup. you'll find plety of information for it on the webmails project pages.

I wonder how exchange licensing works? does it work on how you access the exchange server or does it work by you creating the mailbox on the exchange server locally? I probably going have to set up a different mail server maybe sendmail and using squirrelmail and somehow link the linux mail server with the exchange server.. does that sound right

I haven't sold an exchange server in quite a while, but from what I can remember, you pay per-user with access to the exchange server.

I think what you need is a new mail server, setup a postfix server with webmail and some spamfilter (spamassassin comes to mind) while you're at it. Your users will appreciate that!

The only problem I usually face is that people use the shared folders etc which isn't available on typical linux servers. (Though you might want to look at the Cyrus Imap Server which is supposed to do some similar stuff)

yeh i have a mail gateway running mailscanner,spamassassin, and clamav and that rocks. I figured I needed to set up a mailserver. I see that you listed postfix. Will sendmail work or is postfix beneficial?

Well to be honest, sendmail is (motly due to it's age I think) a bit of a mess to configure and has had quite some nasty security problems in the past. Postfix is a bit simpler (though it still is pretty complicated ) while it maintains full sendmail compatibility. You can see Postfix as a polished and new drop-in replacement for sendmail.

Current editions of squirrelmail I believe can work with Exchange Server right out of the box and it has a very handy command line configuration tool to add modules, select your mail server, etc. Just check out their documentation.

And it is correct about licenses ... Exchange comes with a few licenses ... typically 5 I think, but you are supposed to have one Exchange License per user. It gets costly quick.

I ran it briefly at work and talked them into letting me switch over to Sendmail with Trend Micro's Anti-spam/anti-virus software packages for linux. I recently used squirrelmail to add web mail, and I authenicate it all securely through a windows domain controller using PAM. Global Address books are handled by a LDAP server which is also linked through the squirrelmail interface. It has been a real nice system for going on two years. I would recommend adding a SSL certificate to the Squirrelmail interface though if you are a business. just to be on the safe side. And to use SMTP authenication on your relaying.

I'm fairly certain other web interfaces also support Exchange to some compacity. But, squirrelmail has been my weapon of choice of late.

Sendmail or Postfix? It is a personal preference basically (that's what open source is all about -- choices). I will be using Postfix soon ... since I'm upgrading to the Messanger Suite for Linux by Trend Micro. But, I will likely keep Sendmail around for my email relays.
