| The advantage I find in this, is that I'm on 3 primary listservs, and I | don't want to sort that mail into different folders, or I'll miss stuff. | By having that type of Subj line, it makes my In Box sort into 3 | categories, so that I can read it by list if I want to. It depends upon the subscriber's mail client. Mine, w/o the use of SUBJECTHDR, allows the placement into folders which automatically (WINDOW) open. Unread messages are marked with a bullet. This is extremely easy and useful. Some mail systems do NOT properly REPLY with appropriate SUBJECT: lines prepending various :RE: tokens. /Pete
