Mailio

The imap is using plain TCP, but for the secure connection one must use imaps. It inherits imap API but uses TLS. The authentication methods are: login and start tls. For the login method, the well known port is 993:

try
{
    imaps conn("imap.server.com", 993);
    conn.authenticate("mailio@server.com", "mailiopass", imaps::auth_method_t::LOGIN);
    message msg;
    conn.fetch("inbox", 1, msg);
}
catch (imap_error& exc)
{
    cout << exc.what() << endl;
}
catch (dialog_error& exc)
{
    cout << exc.what() << endl;
}

try
{
    imaps conn("pop3.server.com", 143);
    conn.authenticate("mailio@server.com", "mailiopass", imaps::auth_method_t::START_TLS);
    message msg;
    conn.fetch("inbox", 1, msg);
}
catch (imap_error& exc)
{
    cout << exc.what() << endl;
}
catch (dialog_error& exc)
{
    cout << exc.what() << endl;
}
