Regarding “POP3 quit: connection does not exist”
My hosting co (lonex) has an option in the cPanel “Outgoing Connections Manager” You can use this (if you have it) to specify the IP address of the request and allow it. Mine even shows blocked connections (which were WP failed attempts to get mail). Specify the IP address & if available & at your own risk “allow port 25” this is the SMTP. Hope this helped…somebody!
