Fetchmail, no address associated with nodename

[Aurélien DEHAY]

Hello.

I've installed fetchmail via macports on my iMac. I know this  
question is not macports specific, but maybe someone knows...

ordinateur-de-aurelien-dehay:/etc root# fetchmail -f fetchmailrc -N -v
fetchmail: Avertissement: appeler fetchmail avec privil`eges root est  
d'econseille.
fetchmail: 6.3.5 interroge imap.laposte.net (protocole IMAP) `a Wed  
Oct 18 22:00:12 2006 : r'ecup'eration en cours
fetchmail: 'echec getaddrinfo("imap.laposte.net","imap") : No address  
associated with nodename
'Echec de connexion IMAP avec imap.laposte.net: Unknown error: 0

A "host imap.laposte.net" give me this answers:
ordinateur-de-aurelien-dehay:/etc root# host imap.laposte.net
imap.laposte.net has address 81.255.54.7
Host imap.laposte.net not found: 2(SERVFAIL)
;; connection timed out; no servers could be reached

A nslookup on the same address:
ordinateur-de-aurelien-dehay:/etc root# nslookup
 > imap.laposte.net
Server:         192.168.100.1
Address:        192.168.100.1#53

Non-authoritative answer:
Name:   imap.laposte.net
Address: 81.255.54.7

My resolv.conf has only my ADSL router address (which forwards to the  
real DNS servers). What's the trick? Is it related to IPv6? I'm  
coming from Linux world, and my fetchmail conf is good, the same  
configuration works on my ubuntu box, I'm just waiting about  
migrating my mail configuration to swtich off my linux box...

If anyone has a idea...

Best regards.
