great :-) I added this to our IMP 3.1 implementation w/ one minor change: To be consistent w/ other mail clients, I added the X-Priority header between the Message-ID and the Date rather than at the end of the headers. (after line 756 in imp/compose.php,v 2.369.2.32) Thanks, - Ben >This has been implemented in CVS HEAD: >http://marc.theaimsgroup.com/?l=horde-cvs&m=102270507915229&w=2
