Re: Communication (Mail Gateway concept) with MS Exchange
Hi, I'm coming into this slightly late, but you can use fetchmail to hand-roll a solution or (I expect) to collect mail for IMGate. Fetchmail can collect from a POP3 mailbox and forward using SMTP (fetchmail keyword: smtphost) to an Exchange server on a private ip address on a LAN. To the Exchange server, it's as though it were the mail exchanger for the domain, fetchmail is transparent. So mail gets delivered to individual mailboxes as normal. You can also tell fetchmail not to add any headers, such as Received (keyword: set invisible). If there is scanning in the system, fetchmail can respond rationally to most of the error messages generated. This is a very quick and simple basic solution to the overall issue, but doesn't give you spam or virus scanning. You could set those up on the same gateway machine using a system that (like IMGate) wants to act as a forwarder, scanning and then sending on to another (defined) smtp server (your Exchange machine). There are lots of these about, including IMGate. From a glace at the IMGate website, I'd have thought you could install fetchmail without repercussions. If not, there are other scanning packages available. Exact choice depends whether you want to use a commercial or a free system. PWR. Danny wrote: Thanks for the response.

Re: Communication (Mail Gateway concept) with MS Exchange
Try this http://imgate.meiway.com/ it works with pretty much anything behind the mailgate. I'm currently using it on a FBSD with Postfix, Amavisd-new and McAfee for Unix. Works great. the box does Spam/Virus filtering then passes on the good mail to the actual mail server. If you need to know more, join the mailing list.

Communication (Mail Gateway concept) with MS Exchange
Greetings, I am thinking of installing 4.9R, Postfix, and the latter I have yet to find to have a FreeBSD server communicate as mail gateway with MS Exchange. At this point, I do not want to point MX records to our Internet connection and direct SMTP traffic into our LAN, for many obvious reasons, in addition to our existing configuration - with our Internet email being hosted externally and downloaded via POP3. I would prefer to consolidate down to one (currently approx. 40 separate POP3 user mailboxes for this one domain) catch-all POP3 mailbox at our email host, and then have an app POP3 that mailbox down to a FreeBSD server, perform AV & SPAM processing, then somehow deliver that mail to the appropriate user on the Exchange server based on the headers of the email messages. Anyone experienced, heard, or have any ideas?
