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 ... Devin
