Actually 5321 didn't change the definition of helo (and even 2821 didn't
really change it).

that's nice and constructive.

sure, but it can't be removed from the history file ;-p

do you mix mail from me and mail from Wietse?

don't be upset by the "style". the trailing dot thing has already been
debated here a long time ago. so bringing it again does annoy those who
have seen the old thread. While you're not required to know all the
posts and discussions that happened here, don't be surprised if the
responses you get aren't as "smooth" as you would like. but there's no
hate or animosity.

Anyway, as Noel said, "thanks for your willingness to help...".
