Wed, 16 Apr 2008 06:54:12 +0000 http://mwolf.net/archive/spammers-are-liars/#comment-1775 I had the same problem with my mail-server. Suddenly my mails started bouncing because my IP (which is sold to me as a fixed one) is withing a dynamic range. But I have now chosen to use my ISP's mails server for relay. If you are using Postfix, this is extremely easy... just set "relayhost" to the servername in main.cf. That's it! Everything else works as normal - your server still receives mail, and sending mail also works as normal, apart from being send through your ISP's server first.

But it feels wrong: the whole reason for having my own server is because I want to be able to treat my ISP as nothing but a connection onto the Internet, and in every other respect my server should be a first-class citizen. I've got a static IP, dammit, I'm not some loser with a dial-up! Ironically, because at least some of the servers which flag my mail as spam, do indeed follow my advice and silently ignore me, I don't even know that anything is wrong until people start complaining that I never respond to their mail anymore. If they sent me a bounce message, as opposed to my plea in this blog post, I would at least know what's up. So basically, I don't get bounces when I want them and I get them when I don't.. :-( But on the whole, I would prefer the occasional lost message to the periodic deluge of injustified bounces I get now.

Now I just let someone else figure it out. What you might be able to do is, have your ISPs mail server run as a relay for your mail. The ISPs mail server is probably able to get more mail out the door succesfully. But don't forget to add a SPF DNS record listing the ISPs SMTP host as a valid relaying host for your domain. :P And you’ve just mentioned the number one reason why I stopped bothering myself with running a mail server.
