Devin's Received auth header patch

Back in August of last year, Devin Carraway posted this:

http://www.nntp.perl.org/group/perl.qpsmtpd/2012/08/msg9954.html

And  a very short discussion ensued.=20

I have applied a modified portion of that patch to qpsmtpd-dev. After =
the patch, the # enclosed area in the following header is removed:

Received: from c-76-121-98-64.hsd1.wa.comcast.net (HELO [10.0.1.125])
	(76.121.98.64)
### (smtp-auth username [email protected], mechanism plain) ###
	by mail.theartfarm.com (qpsmtpd/0.92) with (AES128-SHA =
encrypted)
	ESMTPSA; Fri, 26 Apr 2013 02:51:22 -0400

While many mailing list to www gateways redacting email addresses in =
headers, many do not. It just seems imprudent to be publishing that data =
into the headers, as well as having logged it.=20
