Hello,
If I am not mistaken you are talking about this:
The following options are available under Encrypted Connections:
•Allow encrypted POP3 connections: Use this option to enable or disable POP3 messages that use encrypted connections. Auto-Protect does not scan any email that uses POP3 over the Secure Sockets Layer (SSL). Auto-Protect continues to protect computers from viruses and security risks in attachments.
•Allow encrypted SMTP connections: Use this option to enable or disable the SMTP messages that use encrypted connections. Auto-Protect does not scan any email that uses SMTP over the Secure Sockets Layer (SSL). Auto-Protect continues to protect computers from viruses and security risks in attachments.
Hope that answers your Doubt.
