Open SMTP Relay set up MessagingException: 550 Not permitted

Hi Everyone,

Hope you can help me,

I have been working on a project to migrate emails to office 365 (on over 80 customers)

But we are a software development company that uses an Oracle 10g Platform (allows no Authentication through SMTP)

We set up an open relay through BT that works fine in some place but not others :S

When trying to email an email address not send it from a noreply I get an error that says

MessagingException: 550 Not permitted

This is when sending emails to the address that the email relay was set up with and one that it wasn't

If you need any more information let me know.

Thank you and Best Regards,

Gavin
