Is this service+port perhaps assuming SSL at once? Then you probably want
pop3s://, as the normal pop3:// will assume that you start out plain TCP and
the connection gets upgraded to SSL along the way.

This seems to indicate exactly this...

This indicate a bug in libcurl methinks, as if the control connection is not
found to be OK it should not attempt to send the QUIT command over it... but
it shouldn't be a problem that affects your case much.
