The address I gave for Alice is the one that is giving trouble. The correct one for her is shown below RM ++++++++++++++++++++++++++++++++++++++ the 1502amc address is the bad one. the good one is acampbell@scseng.com the exact reason i cant post to the list, as i understand it, is that the listserv recognizes us by our 'from' address, not the 'reply-to' address. unfortunately, my work server will not allow me to change the 'from' address to acampbell, and instead uses our network aliases. however, our firewall now will not recognize our 'inside' addresses if they come from 'outside'. it makes me crazy. so while i can recieve mail from the list as acampbell, i can't send to it even though my reply-to address is right. sigh. alice
