Default slowness in sendmail - 60 second timeout

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

Check your DNS resolution settings - it may be dns timeout.

Since you've checked DNS, try looking at your queue intervals and
timeout settings. If it's exactly a 60 second delay it's probably a
timeout value somewhere. If it's up to 60 seconds, look for the queue
settings in both /etc/sysconfig/sendmail and in /etc/mail/sendmail.cf.

You might also peek at the interfaces on the system as having more
than one IP address can sometimes cause this slowness if not
configured properly.

Also, check the hosts file

Sorry to be more specific - make sure that devcentos5x64.msgnet.com is
resolvable.
