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
