Hmmmmm.... "epic fail" perhaps, but not on Jeff's suggestion to use 
standard submission port.

We recently moved 5200+ users from BQ to BX.  We've always used standard 
submission port (587), but used POP-before-SMTP instead of authenticated 
SMTP on 587.  That changed with the move to BX.  Rather than risk 
freaking out at the last minute we made sure that we communicated the 
change with customers, notifying every user about the date and time of 
the cutover.

Of course, not every user will read and understand, so we did take a few 
support tickets (less than 50!) to walk some users through their changes.

I'm not sure who would have told you to go with SMTP on 26, but I would 
use this opportunity to begin your move toward standardization.  That 
way you won't be stuck with some weird set of procedures and leave your 
customers out hanging in the wind.  SMTP belongs on 25, Submission 
belongs on 587.   The sooner you get your machines and your users with 
that program the better off you'll be.   Then your "next" move (or the 
next time the box YUM updates, or...) you won't have another "epic fail" 
on your hands.
