How do I set up Mail Fetcher?

Gmail allows you to fetch mail from your other, non-Gmail accounts. You'll be able to read email from up to 5 additional accounts, all in one place, and take advantage of all of Gmail's great features. Note that the email accounts you would like to fetch will need to support POP access. Some free email services don't support POP access at this time.

Il server pop che ti crea è fasullo.
Con un indirizzo hotmail ti mette mail.hotmail.com porta 110 che da che mondo e mondo non esiste, o perlomeno non è un server pop3 di hotmail.
