sendmail on server A trying to send email to gmail or other email service and it times out

Trying to get a server of mine to send emails to a gmail account. I can send to my locally hosted email accounts but nothing goes through to a email service I do not host. I have other servers on my network that can send to gmail fine and sendmail appears to be setup the same.

I get time out responses from gmail.

internally I have a BIND server, qmail server and a mysql server. I have a subdomain setup on the DNS server for the server I am trying to send emails with. (originally the hostname was set to local host so I thought maybe it was a rdns rejection)

I didnt think sendmail required much setting up, I swear it was easy the last time I did this.

My problem is somewhat vague and I do apologize in advanced. I am hoping someone might have a suggestion on what to check.

According to this http://mail.google.com/support/bin/answer.py?hl=en&answer=13287 , Gmail requires SSL secure connections.  Everything used to be easier.  Are you sending from a verifiable email address?

Email address is root@sub.domain.com, so no technically, no MX or spf, the main domain does....but that was not the issue. It was my Firewall.

I should have instantly thought of this when I could email internally and not externally........NAT rule in my firewall was missing. Tech who set it up must have used DHCP to setup and install and then changed to static IP at the end, server never needed to talk to the outside world until now.
