1 April 1995 Ottawa Canada I discovered that when I try to quote a message and include what had been its headr in a message I send to my list, blind-l, I get the headers pointing to list, e.g. sender, from or reply-to point to the list error message from the listserv. When I edited the rejected message using q-edit on my pc, I discovered 3 or 4 control a characters on a line immediately above the message i had quoted. OK I have some questions: 1. Is it the control a (decimal 001) characters that signal mail and listserv the lines following are rfc-822 headers and not just plain text? 2. Is it a good practice when quoting a message to just ensure the control-a characters are removed? Or should I prefix the lines which were headers in the message being quoted with comment:? I may have found the reason why some but not all mail sites consistently get mail they send to my list and quote another message with headers flagged as a possible delivery error as there are sender, reply-to or from: lines pointing to the list and other people do it all the time and have no problems. It is amazing the things you can sometimes discover either by accident or without knowing what you are looking for. Brian Lingard Internet [log in to unmask]
