Hi! As we are getting more and more complaints from "normal" users trying to send us emails but being rejected because their mailserver is in MAPS or ORBS, we did set up a webpage with a little explanation and made rblsmtpd's return error message pointing to that webpage. The output of rblsmtpd is now something like this: 553 Open relay - see http://www.epigenomics.com/bounced.php3?reason=http://www.orbs.org/verify.php3?address=12.11.158.146 The patch is based on the RSS patch for rblsmtpd and just inserts an arbitrary string in front of the "http://"; found in most TXT records returned by MAPS or ORBS. The string is passed to rblsmtpd via a new argument -w . You can find the patch on ftp://ftp.epigenomics.org/pub/oss/ucspi-tcp/ Greetings -- Robert Sander Computer Scientist Epigenomics AG Bioinformatics R&D www.epigenomics.com Kastanienallee 24 +493024345330 10435 Berlin
