exim4

[Robin Gerard <robin.jag@free.fr>]

Hello,
I installed exim4 on my box.

There are 3 users:
root
user1
user2

For user1 all is ok: messages being sent and received correctly.

For user2 messages are sent ok, but for the receiving of the messages I get:

1 message for fu.bar (user2) at pop.free.fr (945 bytes)
reading message fu.bar@pop.free.fr: 1 of 1 (945 bytes)
fetchmail: SMTP connect to localhost failed
fetchmail: SMTP transaction error while fetching from pop.free.fr
fetchmail: Query status=10 (SMTP)

However, all is ok for user1 and user2 with exim. (not exim4)
Can someone help me so that exim4 works correctly.
TIA
