I have an archaic phone system that cannot connect to ssl pop3. It requires pop3 for authentication to deliver voicemail. I have ssl enabled on our exchange 2007 server which includes the pop3 and imap services. Can I somehow allow both ssl and non-ssl connections to the server?

Change the Authentication to - "Plain text logon (Basic authentication)" on POP3 properties from Exchange Management Console - CAS server - POP3 settings.

I guess I was wrong on the connection method. I found that it is using SMTP to authenticate. On the Receive Connector "Client MH-MSX", under the Authentication tab I unchecked "Offer Basic authentication only after starting TLS", and running the command "Get-ReceiveConnector "Client MH-MSX" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient".
Port 25 is not open WAN > this server. All mail goes to our spam server (Barracuda) first and then to our Exchange07 server.
Is this causing any instability or security issues? Is this the correct way to use this receive connector?
