Hi there,

 

Asking about this for a friend and current customer.

Emails he's sending to a specific address are not being received and below is the response he's getting.

 

Have seen similar issues reported, but have yet to see what the resolution is/was.

Think it has something to do with Yahoo email servers blacklisting this email server IP..

 

(Have removed identifiable details from the contents below)

Please let me know if these are required for investigation.
