Yeah, in my case of 20+ years in UNIX admin and development, I've become
comfortable with administering sendmail-based systems, and postfix is
the devil not known :)

Up to now I've been of the attitude of "sendmail's not broken, I've got
better
things to do than fix it".  However, I was reading on ADSP for DKIM
(RFC 5617) and in <http://www.opendkim.org/README> there is a discussion
of issues surrounding sendmail's handling of DSNs.  But then, it looks
like ADSP may be contraversial anyway.

Thus the stream of consciousness ...
