Sorry if I'm being a bit slow here but I'm sure you'll appreciate it is
quite difficult to grasp what others are saying via email sometimes. Can we
go over some scenarios to see if I have understood you correctly:

Scenario 1 - No SSL

CURL* curl = curl_easy_init(); //
Initialise curl
curl_easy_perform("pop3://mail.domain.com"); // This will connect
via a normal connection as #0
curl_easy_perform("pop3://mail.domain.com/1"); // This should reuse
connection #0
curl_easy_perform("pop3://mail.domain.com/2"); // So should this

Scenario 2 - SSL

CURL* curl = curl_easy_init(); //
Initialise curl
curl_easy_setopt(curl, CURLOPT_USE_SSL, CURLUSESSL_TRY); // Use SSL
if available
curl_easy_perform("pop3://mail.domain.com"); // This will create
connection #0 and upgrade via TLS if server supports it
curl_easy_perform("pop3://mail.domain.com/1"); // This should reuse
connection #0
curl_easy_perform("pop3://mail.domain.com/2"); // and this

Scenario 3 - No SSL and then SSL

CURL* curl = curl_easy_init();
curl_easy_perform("pop3://mail.domain.com"); // This will connect
via a normal connection as #0
curl_easy_setopt(curl, CURLOPT_USE_SSL, CURLUSESSL_TRY); // Use SSL
if available
curl_easy_perform("pop3://mail.domain.com/1"); // This will create
connection #1 and upgrade via TLS if server supports it
curl_easy_perform("pop3://mail.domain.com/2"); // This will reuse
connection #1

Kind Regards

Steve
