HUB transport Receive Connector not routing mails

[oyazo]

Hello All,

I used exchange 2007 platform.

I have an application that could send mails thru my receive connector on HUB Transport when its on server that sits on 172.19.3.x network but refuses to send same mail when its on client machine that sits on 192.168.3.x network.

Both network can communicate seamlesssly and browse the net.

Pls what could be reponsible for the application not able to send mail on 192.168.3.x.

Thank you.

Sounds like the hub transport server is locked down to only allow email relaying from the 172 network not the 192 network.

What have you tried / checked?
