Re: [gentoo-user] OT: Any interest in a postfix/milter bridge?
every mail filter I need fits nicely into postfix. Which one are you having problems with? and I don't think this is the place to discuss enhancements to postfix, go join postfix-user and discuss it with the developers.

every mail filter I need fits nicely into postfix. Which one are you having problems with? I'd like to be able to run MIMEDefang, but it's milter only. and I don't think this is the place to discuss enhancements to postfix, go join postfix-user and discuss it with the developers. Which is why I marked the subject as OT. I didn't want to post to the postfix user yet because I didn't want to cast such a wide net; the smaller group of postfix users on this list would help me gauge whether to pursue fishing in the larger sea... -- gentoo-user@gentoo.org mailing list

Dave, Having investigated the milter API and having constructed some milters myself, I currently believe that it should be possible to build a postfix-milter bridge. That would be fantastic. I think you would get tons of support for this. I would also love to run MIMEDefang and domain keys milters, etc. that aren't available on pure Postfix. You should definitely post this to [EMAIL PROTECTED] where you'll get more enthusiastic responses like my own, and maybe some guidance from the developers. --- Chris Covington IT Plus One Health Management 75 Maiden Lane Suite 801 NY, NY 10038 646-312-6269 http://www.plusoneactive.com -- gentoo-user@gentoo.org mailing list

I could swear I've said this before, but there are a number of us that use postfix and find this on more on topic than what my favorite window environment might be or how to make an ebuild for a desktop game. So again I'll quietly ignore the things I don't care about and you will do the same. However adding milter support to Postfix may not be the magic bullet. Milters take this path through Sendmail mail queue - milter - delivery | /dev/null | whatever Postfix content filters take this path. mail queue - cfilter - mail queue - etc Allowing people to run what are normally very efficient milters within Postfix may allow a few admins to shoot themselves in the foot performance-wise. In any case you might want to check out this how-to which use Anomy Sanitizer to do basically the same thing. http://www.advosys.ca/papers/postfix-filtering.html kashani -- gentoo-user@gentoo.org mailing list

It's not that I mind the discussion, I just thought it might be better on the postfix-user list as that is a very knowledgeable list and it's where the expertise lies. Perhaps I should have said this is not the BEST place to discuss it... I too use postfix :-) -- Nick Rout [EMAIL PROTECTED] -- gentoo-user@gentoo.org mailing list
[gentoo-user] OT: Any interest in a postfix/milter bridge?
I'm currently running postfix as my mail system. Unlike a recent post which assumed that postfix was overkill compared to sendmail, I tend to feel the opposite, that sendmail is bloated much more than the more simplified postfix. However, when looking for spam blockers, virus checkers, and other message processors, you will typically find multiple sendmail milter implementations as opposed to the postfix filter implementation. Having investigated the milter API and having constructed some milters myself, I currently believe that it should be possible to build a postfix-milter bridge. The milter side of the bridge would support the milter api for compiling sendmail milter-based filters. The postfix side would simply need to wrap a simple smtpd/smtp process that: a) receives mail on the smtpd side. b) pushes the mail through the milter via the bridge api. c) sends the output of the milter back into postfix via the smtp side. Obviously there are some timing issues, etc., to deal with as well as whatever implications there are re: providing a milter-like API for postfix, etc. But assuming these could be resolved, is there general interest in such a beast? Or am I the only one wishing I could integrate tools like MIMEDefang into my postfix email system? I would estimate the building of such a tool to take about 200 hours by leveraging existing smtpd/smtp open source code, and am happy to invest that time if there is some apparent interest in the community for such a tool. I'm just a little leary of investing that amount of my time if there is no real interest in it, just as I would not be willing to invest my time in restoring a Pinto ;-) Dave -- gentoo-user@gentoo.org mailing list
