I don't know fetchmail, but it is always a good troubleshooting step with
mailservers to try to telnet to the tcp port in question and see if it
responds.  IMAP is on port 143 so ....

$ telnet  imap.laposte.net 143
Trying 81.255.54.7...
Connected to imap.laposte.net.
Escape character is '^]'.
* OK IMAP4 server ready (7.2.060.1)

The service looks up.  If you get this reponse from where you are the
mailserver's IMAP daemon must be ok and you must have an application error
or some sort preventing fetchmail from working.
