I had been looking at qmail with clam and spamassassin, but somebody told me that qmail might not be appropriate as a secure mail gateway.

As a side note: I'm not trying to start an MTA war :-) I've used Qmail a long time ago; it's fast, it's very secure, and I liked it. I chose postfix for this particular case because I wasn't doing anything elaborate with the messages and I wanted something that was as "compatible" as possible...the exact configuration for the system I was setting up I couldn't find any simple HOWTOs for, and there is a lot of material for Sendmail and Postfix floating around out there and if documentation said that a particular program, like Amavis, worked with Sendmail then chances were pretty good that it would work with Postfix too since Postfix was designed to be a drop-in replacement for Sendmail. Postfix is also pretty simple to set up, in my experiences. Once I get the server here set up to production level, I'm planning on writing up how I configured it and I'm hoping to get permission to put it in out for people to use as a reference if they have a project like this one to do; I don't know if people would be interested but I know I could have used a guide like this :-) -Bart ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Any suggestions for e-mail gateways. I've looked at postfix and qmail but am not sure that they are appropriate. I could use the built in sendmail, but worry about security. I'm sure either qmail or postfix are perfectly capable of doing what you want - indeed there are many posts about this very subject to the postfix mailing list. I'd suggest looking back through the postfix-users archive to read what has been said in the past. In particular you'll want to consider how to let postifx know what addresses @yourdomain are valid, so that it only accepts emails that are being sent to valid users. An example of how to do this can be found on http://www.plusone.com/gaptuning/postfix/ I looked at both postfix and qmail for dealing with email for my own small email server, and much prefered postfix.
