Welcome to will.harris.ch

This site is a repository for my qmail patches and helper programs, as well as some of my photos..

You can see my main web page at the University of Zurich.

qmail-smtpd.c.diff - a patch to make qmail fully RFC 1870 compliant, i.e. to support the ESMTP SIZE command.
bmf-perl.tar.gz - a patch to let qmail use Perl regexes to check the envelope sender.
