More relevant to LISTSERV(R): if you do generate HTML, the subscribers must have the correct SET (or via DEFAULT) options. SHORTHDR does NOT "cut it." I've also noticed besides the LISTSERV options, that encoding by the browser that sends the mail, or perhaps the client like Eudora that processes the mail is not always "correct" e.g., italicized data when none was specified in the original WEB page; URLs that don't link; URLs with spurious metatags. A problem with emailed HTML is its ability to "hide" the underlying process from the human mail reader. Double clicking on embedded URLs (which might not actually be a URL) could cause damage. This particular "feature" probably is better discussed on the virus (or hoax) forums. /Pete
