We'll assume that an open relay is unacceptable. * Disallow relaying, except for IP ranges you know your users will be coming in on. Pros: no additional configuration on their end Cons: you have to figure out what they are, and depending on how much you can narrow down the ranges, other people on the same range can abuse your server (though not many). I used to work at an ISP that did this for certain customers, and we rarely had a problem with it. * SMTP Authentication Pros: Clean; nobody can use your SMTP that you don't want using it Cons: Additional end-user configuration. Not all mail clients support it (or they don't support it the same way your SMTP server does). More stuff that can go wrong. Yet another password to deal with. * Have your users use their ISP's SMTP server, but still POP mail from you Pros: No additional work for you Cons: Their From: address will be their home email address. This may or may not be acceptable, depending on circumstances. There's other ways I'm not thinking of, I'm sure. Hopefully a magic bullet is among them. :) > 3. whats the best pop3 server to use with this, from what i have looked at > qpopper seems to be quite popular, any other suggestions on this? a few > people have suggested tpop3d but ive not been able to find out much about > it. I use qpopper and am quite happy with it. If you go with qpopper, I recommend using 4.0.3 or better, rather than the 2.53 that's in Debian stable. 4.0.3 is more flexible in its configuration, for one. That, and there's this ominous message on the qpopper home page that says "Don't use 2.53 with Linux!" <shrug> You can get 4.0.3 from www.eudora.com, or from the Debian testing distribution. (If you do that, build it from the deb-src package. apt-get can do that for you automatically. Of course, I'm assuming you're running stable here.) > 4. is there anything else i have missed / should be taking into > consideration? or any other hints / tips to push me in the right > direction.... Oh, probably. But I can't think of them right now. :) Good luck. - Aaron -- So: My point is that [Microsoft] may have a ton of money and be more vicious than a junkyard dog, and have a stranglehold on dimwitted IS managers, but they're just not very _competent_. -- Rick Moen, on macosx-for-users
