Mail config re-vamp

[Jason Pincin <jpincin@ashtech.net>]

OK all - I re-vamped the mail config on our servers.

I removed sendmail from yukon with rpm -e's.

I re-installed qmail on vodka with src rpm's.  Just to make it a little easier to
manage down the road.  In addition to that, qmail no longer runs through inetd...
it runs through ucspi-tcp (ftp://koobera.math.uic.edu/www/ucspi-tcp.html if yur
interested).  This is labeled as "required" for qmail 1.03 though obviously it
isn't as we were running it under inetd.  :)  Figured I'd change it since it was
required for QMQP.

I enabled QMQP on vodka (Quick Mail Queueing Protocol) which runs via qmail
daemons.  

I installed mini-qmail onto Yukon.  Yukon will not answer port 25 requests.  All
outgoing mail from Yukon will be handed off to vodka via QMQP for delivery, by
mini-qmail.

In essence, vodka is our smart mail host, and yukon is a client to it.  yukon runs
no mail daemons what-so-ever.  :)  I like that.
