Cisco PIX config - cannot reach new mail server

I made what I thought would be a very simple change to our Cisco PIX firewall to allow mail and OWA access to our new Exchange 2007 server. We recently added a new Exchange 2007 server into an existing Exchange 2003 single server environment with the intention of decommissioning the old Exch 2003 box.

Here's more background:

I migrated all mailboxes from an old Exch 2003 server (LAN IP: to a new Exch 2007 server (LAN IP: All mailboxes were moved last night. On the LAN I can telnet to all the appropriate ports on the new email server (25, 443, 80, etc). From the Internet I cannot telnet to any of those ports.

I've attached the original config and the newest. All I changed was the line "name MailServer" to "name MailServer". I wrote the config to memory.

Can someone look at this config and tell me why email won't flow into the mail server from the web? I'm at a complete loss.

Thanks in advance!!

Have you tried simply restarting the firewall?

Also what do the logs say when you try to access it?

So what you did was change the translations.  When you do that you need to issue the following command from the CLI:  clear xlate

That will flush out the old static translations and insert the new translations.

Presumably restarting will also do that? :-)

Clear xlate seems to have helped. Mail now flows into new mail server. Outbound mail works as well. Wow I wish I knew Cisco. ;)
