With permission, bringing this conversation back onto the Exim mailing
lists. (Kinda not) sorry for the cross-posts.

Providing a simple commandline for the task at hand was the goal, yes.
I got tired of copying and pasting SMTP conversation arguments to
test things.

Very much so! I did not know about --pipe, and I did not know about
--data either (I simply had not looked beyond the simple uses I had
performed in the past). So to be perfectly clear, swaks already does
EXACTLY what I spent time constructing with expect. And I assume that
swaks, if it receives a 4xx or 5xx at the EHLO, MAIL, or RCPT stages,
will detect it and exit the smtp conversation at that point. I'll
test to make sure.

It was simply a lack of awareness of swaks capabilities on my part.
Now that I know, I will use that instead :-) Thanks John!
