[exim] Permissions problem

Dear all,

since Sunday evening after updating Debian I've been having trouble
with Exim: mail is not being distributed to local users.

From the log I can see why this is happening:
2007-09-11 11:05:11 1IV3YE-0001MQ-Fe == user@???
R=local_user T=mail_spool defer (13): Permission denied: failed to
chdir to /home/confixx/user

But I can't seem to resolve the problem. I've checked the permissions
on the directories and they don't seem to have much effect.

My users all belong to the group "poponly" and Exim4 is running as
Debian-Exim

Very grateful for any help on this.

Charlie
