ok, i was reading about the services ports pop have 110 for pop proxy and 7110 for pop in admin console.
i tried with 7110 (checkin TLS in thunderbird) and worked.
im a bit confused but maybe i need to read the entire manual

sorry this is my first time installing this product, and btw is great, better than any other that i was using, im thinking on changin my production server with this if all the tests goes right
thanks, and if somebdy explain me why i need to use 7110 and not 110 i will be great....
thanks again
