Mario, Something to check is your DNS settings on the Exchange server and whether your Exchange server is permitted to make DNS queries through the firewall. There are instances where Exchange will wait to get a DNS response before sending a message out. If Exchange has to wait for the DNS requests to time out, that can slow down the sending (and probably receiving).

I have a mailserver (Exchange) running in the internal network behind a FW-1 running on NT 4. The static working Ok and the emails are getting in and out. Routes and arp statements are configured Ok on the firewall server. The problem is that the messages are taking a lot of time to leave the Exchange server. The queue fills fast and the emails take a lifetime to leave it. Is there any possibility of the FW-1 be the one to blame on this? The web browsing (using dynamic NAT) with no performance problems. I know this may be simple for the most of you guys, but help would be appreciated. Thank you. Mário __________________________________________________ Do You Yahoo!? Yahoo!
