I've been using mini-qmail on Bering (per Hendry D. Lee: http://sourceforge.net/tracker/index.php?func=detail&aid=586953&group_id=13751&atid=313751 ) but recently discovered that mail addressed to me in the form "postmaster@[1.2.3.4]" was being rejected. I tested this because of what I read at anti-spam Distributed Server Boycott List (http://dsbl.org/) concerning their emails to admins of blacklisted servers. They will only attempt to send mail addressed as above. Other RBLs might be doing the same.
When mail is addressed to my domain (let's say "dork.face.name"), mini-qmail on the firewall compares the domain to the allowed delivery domains in /var/qmail/control/rcpthosts. If it's in there, mini-qmail will forward the mail to the main mail server behind the firewall ("server.dork.face.name"). Naturally, at least "dork.face.name" would be one of the domains in rcpthosts. When mini-qmail receives email addressed to the firewall's external IP addie, it replaces the IP with a domain name and forwards it to the mail server. Unless otherwise specified, mini-qmail will replace the IP with *its own* fully-qualified name (in my case "firewall.dork.face.name"), which, of course, is not going to be delivered on the firewall, so it gets rejected. The fix is to put "dork.face.name" into a new file /var/qmail/control/localiphost. If this file exists, mini-qmail will replace the IP addie with the dork.face.name domain, compare the resulting address with the list of domains in rcpthosts and, lo, there is a match. The mail gets forwarded to the server. Hope this helps if you're using mini-qmail and get blacklisted :-) -John __________________________________________________ Do you Yahoo!? Yahoo!
