Senario:
Win 2000 server sp4
Exchange 2000 server build 6249.4 sp3
SonicWALL TZ170 (latest firmware)
Dlink 504t (latest firmware)
1000/256 ADSL (Eircom.Net)
Everything works fine, Web Browsing, etc. All mail is being delivered except from messagelabs.com
I have setup dozens of Exchange servers with SonicWalls and Dlink 504t routers in the UK. However, this setup is in Dublin using Eircom.net
I have had to drop the MTU values from the default 1500 on both Sonic and Dlink in order to web browse and receive emails. I have tried various MTU settings (currently 1404)but I still get "451 Timeout waiting for client input" on any email bounced back from messagelabs after 7 days.
The customer in question does not use MessageLabs themselves.
Any suggestions???
Thanks
Graham
