I have a POP3 connected exchange server in windows small biz server that is having issues downloading messages larger than about 2 or 3k.

Its been service packed to SP2 for exchange, the server was working just fine till the client updated thier DSL circuit. Nothing else has changed. They can surf the web and ISP states they are not blocking any ports. An Outlook client that is pointed to the ISP has the same issue. We have set the DSL modem to point to the sonicewall firewall to be the DMZ in addition to setting specific rules for the the various ports: 3389, 4125, 25 etc.

Since the DSL has been changed/updated, I would suggest this is an MTU problem on the router. Check with the ISP for their recommended MTU setting and update the router accordingly.

With an outlook client pointed directly at the POP3 server but behind the firewall the email would simply not download if was of any size.

As a test I removed the sonicwall and set the clients DSL (actiontec) router to be the firewall and recreated the rules and re-IP'd the LAN side to match that of the server's subnet.

The email started to flow. Seems the sonicwall took a dump, not sure why but think its just coincedence.

I will do a factory reset on the sonicwall when the client is ready, but they may need a new firewall.
