Relaying Prohibited

[lewishardwick]

Hi there peeps, here's one to tax you, becuase its taxing me!

Have outlook express running on various networked PC's in my office.

They are all controlled by WinRoute, and they al link back to a central PC (not a server). every machine bar one can send e-mail. Every time I goto send I get a Relaying Prohibited message, but I can recieve mail no problem.

Any ideas?

Many thanks!

Is there an IP address restriction set on the machines that can connect to SMTP? Is this other PC in a different IP range to the others?
