When Eudora displays "From ???@???", that typically indicates (as you might guess) that Eudora couldn't find, or couldn't parse, the "From:" line. Why that would happen is a different matter, particularly if other people are not having similar problems. This is probably a cop-out, but if I could see the full headers of one of the affected messages that might give me more to work with. I suppose it's possible that for some reason the post-processor you're using to replace the 'From:' lines is occasionally doing it in an invalid way, perhaps not using the proper end-of-line indicator or some other nonobvious problem. LISTSERV typically follows all relevent RFCs extremely well. I don't remember what LISTSERV does if it's given a message with a bad From: address to distribute to a mailing list; I _think_ that it bounces it to someone in power and doesn't distribute it. Maybe someone who's encountered the problem recently can say more about this. (Or someone from L-Soft, of course.) There isn't too much information, but I retain the illusion that I may have been helpful in some way. I hope that this is the case. -jwgh -- One day a tortoise will learn how to fly. - (Terry Pratchett, Small Gods)
