Emailing problem with TidMessage [D7/INDY/EMAIL]

[StellaIndigo]

OK I've got an odd message deleivery problem with an app. (delphi 7, using TIdSMTP and TIdMessage, Win2K and Exchange 5.5)

When the recipient is within my domain everything works OK. If however I address someone outside my domain I get a delivery failure. Outlook to the same external address from the same machine works fine.

So this works OK:

myMessage := TIdMessage.Create( nil );
toRecipient := myMessage.Recipients.Add;
toRecipient.Name := 'Me';
toRecipient.Address := 'me@mycompany.co.uk';
.. do the send ..

While this will fail:

myMessage := TIdMessage.Create( nil );
toRecipient := myMessage.Recipients.Add;
toRecipient.Name := 'Me';
toRecipient.Address := 'me@athome.co.uk';

Any ideas

OK sorted this problem.

As a good sysadmin I have relay/forward SMTP traffic turned OFF on my exchange server. I've now changed it to authenticated users only and used

idSMTP.AuthenticationType := atLogin;
idSMTP.Username := 'myname';
idSMTP.Password := 'mypassword';

on the TidSMTP object and it works ok.
