I'm not clear that there is a dns/host entry for devcentos5x64.msgnet.com on
devcentos5x64.msgnet.com. I would make sure that there is an entry for this
host on devcentos5x64.msgnet.com. If there is then apologies for not getting
it :-).

I think that sendmail is checking the "MAIL" command - there are no
timeouts that are specific to this rule afaik and sendmail would use a
timeout of 1 second (which is doubled to a max of 4 mins) if this was an
issue with bogus commands or repeated commands. From your description, it
"feels" as if there is a problem with the name resolution of
devcentos5x64.msgnet.com. You may wish to enable FEATURE(delay_checks)dnl in
the sendmail.mc and rebuild the sendmail.cf file and see if it helps. If
this makes a difference then I would look in the MAIL command checks.
Simon.
