Here is the result of the CAPA command (I changed strings for privacy):

	yves@Voyager:/soft/.install/Sources/02-WEB/01-Fetchmail$ telnet <the_server> 110
	Trying <the_server>...
	Connected to <the_server>.
	Escape character is '^]'.
	+OK Microsoft Exchange Server 2003 POP3 server version 6.5.7226.0 (<the_server>) ready.
	CAPA
	+OK Capability list follows

	USER

	+OK
	QUIT
	-ERR Logon failure: unknown user name or bad password.
	QUIT
	+OK Microsoft Exchange Server 2003 POP3 server version 6.5.7226.0 signing off.
	Connection closed by foreign host.
	yves@Voyager:/soft/.install/Sources/02-WEB/01-Fetchmail$


Here is the fetchmail configuration file:

	# Configuration created Thu Sep  8 16:40:38 2005 by fetchmailconf
	set postmaster "yves"
	set bouncemail
	set no spambounce
	set properties ""
	set daemon 30

	poll <the_server> with proto POP3 auth ntlm
	       user 'username' there with password '*******' is 'yves' here options pass8bits

The problem seem to be with the authentication. Exchange interpret the
string "auth ntlm" as "auth msn"!

Here is the results of the command you asked:

	yves@Voyager:/soft/.install/Sources/02-WEB/01-Fetchmail$ fetchmail --nosyslog -Nvv -f .fetchmailrc.0
	fetchmail: démarrage de fetchmail 6.2.5 en tâche de fond

Thank you,
