please excuse the c-serve return e-mail but that's my most reliable mail
server!

 QUESTION1:  I have a server called mailhub.pensacola.com which is the same
    machine as pensacola.com; ipaddress is 206.96.254.1
    mail to pmain@mailhub.pensacola.com works while
    mail to pmain@pensacola.com causes a loopback error

   Have tried several combinations of mx records and even NO MX records
   in the DNS mailhub is also running dns and tried running without.

  What's crazy is there is another machine with nearly identical
  configuration called mailhub.amaranth.com which does do all the above
  correctly for amaranth.com  <go figure>

  All programs on pensacola.com are from SLACKWARE PRO version 2.3 while
 the amaranth.com machine has programs dating from an earlier slackware
 that came with the 1.1.59 kernel.  <that's another story!>
 anyhow the admin for amaranth is not very knowledegable on linux and
 networking issues which is why i have been called. dns and sendmail are
 not my strongest suit
    ANY SUGGESTIONS?
   please send a copy of replies to 72254.3077.compuserve.com but i do
   usually get most messages posted here!

 QUESTION2: WHILE WE'RE AT IT what is the proper way to get pensacola.com
 to receive mail for a totally different domain such as teacher.net I do know
 that i can create a CNAME entry for say: mail.teacher.net that would cause
 mail.teacher.net to be an alias for mailhub.pensacola.com and all would work
 how could i get pensacola's mailhub to accept mail like: pmain@teacher.net??

 RTFM .... yes i know and the O'Reilly books are on the way even now. BUT
   surely somebody already has this setup already. perhaps a hint? :-)

 ps: the masquerade seems to be working very well for another client! 1.3.35
and 1.3.45
