I believe the term “connector” is a Microsoftism and best I can explain it is that it’s a collection of abstractions of various types for connecting email systems. I use some for sending trusted email from on premise Postfix servers to several O365 accounts. I specify the source IP addresses, or the CN of the TLS cert I’m using, in the connector configuration, and a number of capacity controls, filtering for spoofed return addresses, etc. no longer apply. I’ll note that MS appears fairly serious about depreciating anything other than TLS 1.2 with “real” certs and I validate their cert and have them validate mine. Of course, my email is flowing in the opposite direction of the OP’s. —Jon Radel Please do not use e-mail to transmit orders for securities or for other time-sensitive messages.
