Re: Receive Connector authentication and Permission

but this wouldn't inhibit mail from flowing, right? TLS is opportunistic I
thought. As long as I allow anonymous connections via the permissions tab,
shouldn't the connection be able to be established?

-authmechanism is set to: Tls, Integrated, BasicAuth, ExchangeServer

You want -AuthMechanism to have None among the options unless you have some
way for the servers to authenticate. If both servers support it, i.e., have
certificates installed (on the Exchange 2003 virtual server and the Exchange
2007 send and receive connectors) you can try to make TLS work. That would
be a recommended configuration if you're at all concerned about security.

Exchange 2007 trying to communicate with a business partner's Exchange
2003
server over a trusted internal network. No firewalls in between, can
telnet
to port 25 both ways. I believe I just have the Exchange 2007 receive
connector setup incorrectly, as the Exchange 2003 server recieves mail
from
the 2007 server fine. I used Custom as the type when setting it up, but
then
modified it with the following settings:

Authentication set to use Basic, Exchange Server Authentication and
Integrated Windows. (But I think originally when the connector was
created
it was using TLS and I removed it)

Permissions are: Anonymous, Exchange users, Exchange servers and Legacy
Exchange.

I got an error, event ID: 12041 complaining about TLS cert?
