I administrate an MS Exchange box and I have looked around for some Exchange modules but haven't found any. But like they said above, you can install the smtp connector and use any of the Perl Mail modules to send mail.

If you aren't sure if your Exchange server has the smtp connector installed, just telnet to the Exchange box on port 25, if you get a response like this:

220 exchangeserver ESMTP Server (Microsoft Exchange Internet Mail Service 5.5.2650.21) ready
250 OK

Then you know you have it. Same goes with POP, just telnet to port 110.

Now, if you want to send mail within your organization (from exchange box to exchange box) and want to use some of the Exchange features, then I think you are out of luck. MS uses .X400 for talking between Exchange boxes and I'm not sure how closely they followed the standards for that.

If I had more time I would love to start some Exchange modules.

sigh.

Thanks,
