Apparently the powers that be don't want informational messages to be part of the 'In-Reply-To:" fields anymore (http://www.faqs.org/rfcs/rfc2822.html).
The obsolete fields could look like: In-reply-to: Your message of "Fri, 27 Jun 2003 13:35:24 EDT." <[EMAIL PROTECTED]> which is what nmh puts in by default. Now only the information in the angle brackets is to be supplied. Should we change this? Thanks.
