First guess would be a DNS configuration error that would cause other mail servers to drop your outbound messages (as spam); does other mail from that mail server get delivered?

nope that's all fine, all other emails go out fine and the server runs eveerything else fine it's just external invites.
DNS forward and reverse OK
PTR in place
Thanks, I wonder what it could be..

OK I found out what it was, if you have a contact in an address book, it looks like Calendar server sends to the top email address, even if you put in one of the others in the contact profile...
Odd never saw that before.
