5.7.1 Unable to relay
We have built an application that sends an email with a pdf attachment to certain email addresses. It sends ok to internal email addresses within the organisation but when sending to an address oustide of the organisation it sends a message to the administrator as outlined below. The exchange server is set to allow relaying for all computers that authenticate (it wasnt but having looked up possible senarios yesterday on EE I tried it) The VB code seems ok & the user it is using to send the code is a named user on the exchange server & has a mailbox. If I sign on as the same user into exchange & forward it to the external address it works fine. Anyone any ideas?

Wat if we telnet from the SQL to exchange on port 25 and try the same thing??
ASKER
I cant remember the telnet commands once I am connected :(
ASKER
Ignore that just had a refresh!
If I telnet from the SQL server to an internal address it works fine, if I send to an external address I get the 5.7.1. unable to relay
