No. } Follow up question, If I have to fold the headers myself, will } action_add_header } or action_change_header change the standard \n end of line into an RFC } compliant <CR><LF>, or do I need to explicitly insert them? I use this: use Text::Wrap (); sub wrap_header ($$) { my ($hdr_name, $hdr_data) = @_; my $hdr = "$hdr_name!!$hdr_data"; # use '!!' instead of ': ' so it doesn't wrap on the space $Text::Wrap::columns = 79; $Text::Wrap::huge = 'wrap'; $Text::Wrap::break = '(?<=[\s,])'; $hdr = Text::Wrap::wrap('', "\t", $hdr); return (split (/!!/, $hdr, 2))[1]; # just return the data part } You call it like this: $status_header = wrap_header("X-Spam_Status", ($hits < $req ? "No, " : "Yes, ") . "hits=$hits required=$req tests=$names autolearn=$learn " . "version=" . Mail::SpamAssassin::Version() ); I basically swiped this from SpamAssassin. You can learn all sorts of things by looking at the SpamAssassin source code. }-- End of excerpt from "Damrose, Mark" _______________________________________________ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list MIMEDefang@lists.roaringpenguin.com http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
