Our Hosted Exchange service provider has just migrated our accounts with them from older exchanger server to new 2010 exchange system.. we are all geting our emails..but we have to change our SMTP settings from port 25 to port 587 plus a new address.. I am not able to get anything that required SMTP to work (such as Backup Exec Notifications and Sharp printer Scanning to email) and I need to know if our Netgear FVS338 Firewall/VPN router is blocking it. I can not see anything obvious in the settings. Though Outbound All appears to be allowed.. Wondering if there is a Port tester or tool that I could run to see if the Port is the issue?
