Anyone else use an external pop3s account with a Network Solutions wildcard ssl cert? The Zoho mail tool keeps throwing an openssl error like:

pop3-login: SSL_accept() failed: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown [72.5.230.103]

Weird thing is all other external mail clients work just fine with no ssl cert errors. Any ideas?
