Now that an??? is alleged to be off the list, I'll post this; I sent it to Hugh earlier, but it should be of use to anyone running a security-related majordomo: It should be simple enough to change RetMailAddr in majordomo.pl; right before it returns $ReplyTo, adding $ReplyTo =~ s/an(\d+)@anon.penet.fi/na\1@anon.penet.fi/; will switch an* addresses to na* ones... This lets an address subscribe, they just get automatically converted to na forms. (Alternatively, one can always drop in an abort in the ValidAddress function (if I remember that name right) to just abort on anything that matches penet.fi, but that would be rude, and merely escalate the problem...) _Mark_ ps. Has anyone added pgp support to majordomo? I might consider it... there are lots of issues -- but change the subject line if you want to talk about it on the list :-)
