Just by following the links from the main Postfix page I stumbled across this little thing for FreeBSD: http://www.flakshack.com/anti-spam/wiki/index.php This alone is way to much to do but the part about installing and configuring Postfix is the minimum you need to have that Postfix gateway up and running: http://flakshack.com/anti-spam/wiki/index.php?page=Installing+and+Configuring+Postfix Another documentation describing how to setup an gateway (this time with SpamAssassin) is the one from the Gentoo Linux distribution: http://www.gentoo.org/doc/en/mailfilter-guide.xml It as well describes basically what needs to be done to get an filtering gateway. Those principles described there are valid for DSPAM too. Another one targeting Gentoo Linux and DSPAM in relay mode: http://en.gentoo-wiki.com/wiki/Dspam_relay And again another one for Gentoo Linux and DSPAM: http://devnull.com/kyler/dspam.20040512.html You don't even have to go and search the net for howtos since even the Postfix main page has informations on how to setup an Postfix gateway: http://www.postfix.org/STANDARD_CONFIGURATION_README.html#firewall See that link above? STANDARD CONFIGURATION. Standard. Such setups are nothing special. In German I would say: 0-8-15 (when some one says 0-8-15 in German then this means that it is normal. Like you would tell me that you jumped 3 meters (thinking that this is something ultra special) and I would respond: "0-8-15" (meaning: Average. Normal. Nothing special. Not worth mentioning it. etc...)) etc, etc, etc... there are thousands of howtos out on the net telling you how to setup an gateway with Postfix. Just use any ine of them to setup a Postfix system. Don't care about DSPAM. As soon as you have that Postfix gateway up and running then adding DSPAM is really easy (probably less then 5 to 10 minutes work). I don't remember how many Postfix systems over the years I have put in front of various other MTAs? Many, many, many. Your mail from this morning got me just on the wrong foot. You wrote so bold that DSPAM is the problem and that it can not be an easy way to setup something like that with DSPAM since there is no documentation, etc... that got me somehow furious. Searching two weeks? TWO WEEKS? Where the hell have you searched? The net is flooded with howtos about gateway setups with Postfix. It is pretty hard to not find a document describing how to put Postfix in front of Exchange, Lotus Domino or any other MTA out there. Just take them and get that Postfix gateway working. Just that. When you have that working then (I repeat myself) adding DSPAM is easy as 1-2-3. Most of those howtos about Postfix gatways are small. Not because they try extra hard to be small. No. It is not that. It is just that setting up an Postfix gateway is really, really, really not much work. Just querying Google with "Postfix gateway" should deliver enough info: http://www.knowplace.org/pages/howtos/smtp_gateway_for_multiple_domains_with_postfix.php http://beginlinux.com/server_training/mail-server/1044-postfix-mail-gateway http://www.howtoforge.com/linux_spam_filter_mail_gateway http://www200.pair.com/mecham/spam/ http://goodingredients.org/recipe/articles/email3/postfix-gateway.html Those 6 links from above where all on the first page when I googled.
