Can't get POP3 retrieval to work

I read every post on this forum talking about that and tried many things but tickets are never created and mails stay in the pop3 mailbox . . .
I tried :
1. to access the account with thunderbird. Worked flawlessly.
2. in the "Pop3 Host:" i tried :
pop. orange-business. com
pop. orange-business. com:110
pop. orange-business. com/pop3
pop. orange-business. com:110/pop3
3. surf to hxxp: mydomain. com/eticket/automail. php
I got a blank page, source code is empty.
4. i added a cron job :
*/15 * * * * wget -q -O /var/virtual_www/logs/eticket-automail. log hxxp: mydomain. com/eticket/automail. php
Here is the content of eticket-automail. log :
--2011-12-19 17:29:01-- hxxp: mydomain. com/eticket/automail. php

No new tickets, never ever.
I don't know what to do or where to look into. . . Any idea anyone ?
