[BlueOnyx:06811] Re: changes to sendmail.cf from BQ?

[Roy Urick]

Sorry, my apologies to Jeff for such a terse response . As you can imagine
stress was a bit high last night/this AM, and a suggestion to suddenly move
that many clients on the fly wasn't within reason. 

We did the best with what we had, as at the time the decision was made  many
years back the server at that time  didn't support submission port.  Since
then we haven't changed. 

Hopefully our next move will be to Exchange 2010 later this year. *crosses
fingers*

Thanks to all for your help. Larry hit the nail on the head with the
sendmail.mc file. I forgot that's where I added it last time.

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.
