No, I'm saying that the syntax you are using is wrong.
It's defined in RFC 821 and its successors (RFC 2821, ...)
It's not relevant here, but it's just something that I correct
whenever I see it (it's bad behaviour and a real MTA doesn't
accept that kind of broken syntax).

"ff" is used in citations to say "and the following pages", I abused
it here a bit.

Still wrong, no space after colon.

That's interesting...

Try this:

sendmail -bt
/tryflags hr
/try esmtp kmcgrail_at_talon1.pccc.com
/try local kmcgrail_at_talon1.pccc.com
