Paul,
  I think you want to look at turning off "preserve_local_plus_detail" in
your sendmail configuration.  See:
  http://www.sendmail.org/m4/features.html#preserve_local_plus_detail
for details.  I would strongly recommend testing this before using it in
production, since I'm not sure what else turning this off will do.
  A line like:
	define(`_PRESERVE_LOCAL_PLUS_DETAIL_', 0)
after the line that defines cyrus2 as your local mailer in your mc file
certainly seems to take out plussed-user support.
  Hope this helps, but if it eats all of your email and causes your server
to disapparate, my employer and I are not liable. :)
