[CentOS] slowness in sendmail - 60 second timeout

Jerry Geis <geisj at pagestation.com>

I am sending an email from my machine devcentos5x64.
the transcript below (hangs for 60 seconds) at the line:
MAIL From:<root at devcentos5x64.msgnet.com> SIZE=56 
AUTH=root at devcentos5x64.msgnet.com

The email succeeds - but I am trying to figure out the 60 second delay.
Neither email server is busy. Nothing is waiting.

the DNS on both machines point to the same nameserver. The DNS responds 
very fast when looking up server names.

What else can I look for to remove the slowness or delay?
