Patch for qmail
Any information on this page may be outdated or otherwise inaccurate. Links may be broken. It stays here for historical reasons.
This is a patch to lookup MX-records before relaying.
A friend of mine is running Exim on his server and doing seconary MX for us. Exim has a feature to check if it is inscribed as a MX at the domain it should relay to. Take a look to the documentation of Exim (look for @mx_secondary and @mx_primary). I've seen this configuration by my friend and wanted something comparable for qmail. Here it is. :-)
But… rcpthosts exists?
Yes, it does. But if you have to add/delete domains often on some/many secondaries, you maybe want to look for another solution. With this patch, you have only to add the secondaries to the mx-list of your domain (what you anyway have todo :-)) and the secondary will automatically relay to this domain.
The patch
To use this patch, it is required to patch rcpthosts.c, qmail-smtpd.c and Makefile. Because Makefiles often differs between different distributions, I provide two patches for Makefile, one for Debian and one for Gentoo.
Download
Note: Gentoo users can simply install >=qmail-1.03-r15, the patch is included in there.
