Can you update the text for this (or point me to the proper way/persons
to do this)?

"sendmail through at least 8.14.7"
sendmail up to and including 8.17.2

remove the seemingly unrelated reference to
"Merge sendmail 8.14.8 to HEAD  freebsd/freebsd-src@...76dd"

Mention that 8.18 fixes the problem:
	Accept only CR LF . CR LF as end of an SMTP message as
		required by the RFCs when the new srv_features
		option 'o' is used.

sendmail is available at
