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.
|- a patch to the mess822 package ofmipd to support DNS envelope sender checking as well as mail size limit enforcing through an additional databytes control file.
|- a patch to make qmail fully RFC 1870 compliant, i.e. to support the ESMTP SIZE command.
|- a patch to let qmail use Perl regexes to check the envelope sender.
|- a system-level filter designed to check incoming mail against spam blacklists and flag the mail on the subject line and with X-Blacklisted headers.
|- a patch to insert an X-Remote-IP header in all mail.
|- command line tool to check IP addresses against DNS-style blacklists (e.g. RBL, RSS, ORBS, DUL). By [email protected].
