Re: report-xemacs-bug?

I have some findings to add following up on a thread mostly between Vaclav Barta and Adrian Aichner, http://list-archive.xemacs.org/xemacs-beta/200110/msg00078.html The difficulty sending out mail doesn't have to do with Vaclav's local mail setup. It is specific to Xemacs; Gnu emacs (on the same machine) doesn't suffer from the problem. I have RedHat 7.2 and the "normal" variables in emacs: send-mail-function sendmail-send-it sendmail-program "/usr/lib/sendmail" Gnu emacs invokes sendmail -oi -f christian(a)xpogen.com -oem -odb -t which is good. But Xemacs invokes sendmail -oi -f brech -oem -odb -t and THAT'S BAD! Because now sendmail puts in brech(a)localhost.localdomain as the Return-Path, and many mailers will reject the message as they cannot resolve the originating domain. By the way, * Supplying Return-Path: as a header in the message does not help; sendmail overrides it. * Gnu emacs has "/usr/sbin/sendmail" as the send-mail-program, but changing that has no effect. * I'm serious about mail in emacs. I've been using VM for years. And, the Return-Path problem is unrelated to VM. Question: How can I influence what Xemacs puts after the -f option to sendmail? Thanks Christian
