I have a linux debian with apache and virtual hosts and I want to use
exim .
I use some .lan for the moment because I haven't domains yet : so I use
it in LAN , the virtual hosts work with apache but not with exim.
But I have a pb :

root@clara:/etc/mail# exim -d -bt skyce@???
Exim version 3.35 debug level 1 uid=0 gid=0
Berkeley DB: Sleepycat Software: Berkeley DB 2.7.7: (08/20/99)
LOG: 0 MAIN
lowest numbered MX record points to local host: clara.lan (while
routing <skyce@???>)
skyce@??? cannot be resolved at this time:
lowest numbered MX record points to local host

Of courses I have a dns server with an MX record pointing to clara,
clara.lan is the virtual domain.
Many thanks for your help.
