Exchange Server Unencrypted Login/Password w/ POP3

We are currently using Chilkat to retrieve e-mail for a number of our applications.

A client of ours has updated their exchange mail server and they have disabled the pop3 service because of authentication issues (the user/password is sent unencrypted and would be a threat). Are there any other possibilities within the scope of chilkat to retrieve mail from an Exchange Server without these drawbacks?

Your client may enable POP3 w/ SSL/TLS on the Exchange Server. POP3 over SSL/TLS is secure and the password is passed over a TLS encrypted channel. The standard port for POP3 over SSL/TLS is 995, and Chilkat fully supports it.
