I knew about this one because it didn't have the <> around it.

Thanks for that correction! I thought I was intimately familiar with
5321 and 5322, but I had overlooked that space requirement.
I guess it would be worth mentioning that all versions of
sendmail (sendmail 8.13.8 on stock CentOS 5.x boxen and
sendmail.8.14.4 rpms that I build) accept it with that space. The
above test was to "220 mail.mrball.net ESMTP Sendmail 8.13.8/8.13.8;"
so while the RFC specifies it, sendmail and exim both chomp the spaces
out and accept it. I assume that's the "be strict in what you emit
and liberal in what you accept" mindset in action.
Have a great day!
