Here's an example from the Andrew Messaging System in 1992. The Cyrus
+suffix addressing was inherited directly from AMS.

Here's someone asking how to do it with Procmail in 1995, which indicates
it was a well-known feature by then - plus a follow-up thread which
indicates support in Sendmail.

And there's the .qmail stuff which seems to have been there right from the
start, in early 1996. Ian's message implies that this predated and
possibly inspired Exim's support for filtering on local_part_prefix/suffix.

I don't think I got stuck in to Exim until 1997...
