Due to the exponential increase of spam, we generally have to reject all messages which are not secured by SPF or DKIM, and we know a lot of other people who do the same (by the way, this has proven to be extremely effective in our case). When our MTA encounters such a message, it rejects it and returns a bounce message to the pretended sender, notifying him about the problem. Of course, we absolutely do not want those DSNs to get onto the mailing lists, so we have to implement exception rules for every mailing list which does not use SPF or DKIM. This generally works, but it requires some manual effort, and it only works until a mailing list server changes ... Given that, I think that other people would be grateful if you would implement one of those techniques, too, and implementing is very easy :-) Regards, Binarus ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
