we have a postfix server that uses SASL and we are trying to relay the box through an eexchange 2010 server but it keeps spitting back errors 
 
(delivery temporarily suspended: SASL authentication failed: server mail.mail.com[1.1.1.1] offered no compatible authentication mechanisms for this type of connection security) 
 
This was using an account on the server to authenticate and it still failed... 
 
 
(delivery temporarily suspended: host mail2.mail.com[2.2.2.2] refused to talk to me: 421 4.3.2 Service not available) 
 
 
server mail2.mail.com is set as a relay with Ip restrictions, the IP's are in the allow list but this error still pops up 
 
 
I had issues setting up this receive connector in this thread

Any thoughts on this and what i may need to still set?
