Failure sending mails using Microsoft Exchange
- by Yves
Hi,
I seem to have a problem configuring my Microsoft Exchange to send mails outisde of the domain. I have setup my smtp connectors and everything else. I can receive mails but I can't seem to send any. I keep getting #5.5.0 smtp;550 Sender verify failed
Anyone has an idea how I could fix that?
Regards,
Yves
