Actually, I found that stopping and re-starting the mail services using the
supplied command line code:
/etc/init.d/sendmail stop
killall -9 sendmail
/etc/init.d/sendmail start
Via remote access using the Java application (Mindterm) thru the GUI has
solved the problems I encounted regarding email each time I set up a new
domain on my two new servers running BlueQuartz.
I was trying to accomplish the same thing by un-checking, saving,
re-checking, saving the mail server through the GUI but that did not work.
Maybe a "button" thru the GUI in a future BlueQuartz update pkg that does
that same thing as the three lines of code above would be a handy item to
stop and restart the mail services, but no big deal to use the command line.
The main thing is knowing that there is an issue and to stop and re-start
the mail services after you add a new domain and users if one is having mail
issues.
Thanks!

But the second hint was the solution... OMG i didn't know that C-NAMES
are THAT EVIL!
Thanx again Michael!
