e time.  I was the
document editor for RFC 5537.  Both of these documents are built on
<a href="rfcs/rfc5322.txt">RFC 5322</a>, the current standard for mail messages.

These RFCs obsolete the previous standard for the format of Usenet
articles, <a href="rfcs/rfc1036.txt">RFC 1036</a>, and the draft document known
as "Son-of-1036" which was published as <a href="rfcs/rfc1849.txt">RFC 1849</a>
