domain email addresses and SMTP Server

[doubleclick]

Hi... I have setup a Send Email script (basically from your sample database) and am having strange results when sending from 2 different computers.

If I send from the computer hosting FileMaker (as a client) the plug in sends fine using email addresses from within the SMTP domain. eg. [email protected] and external email addresses.

 

If I send the same email from another computer it returns an error that the email address is incorrect, but only when I use an external email address. Internal addresses are sent and received fine.

 

Is this perhaps a problem with the SMTP server settings?

The IT GUY has said that it had something to do with the RELAY :-) It is now sending from all machines.

I'll post some more "technical" reason for it when he emails me.
