I have checked /var/lib/named/etc/named.conf and named.conf.include,both look OK to me.
By the way, i do installed KDE with x-window decktop with this Dell ISP server, will that cause any problem?
for the mail box connecting problem, same error after running newaliases. also on the mail log "Dec 16 19:01:21 tadj2 dovecot: dovecot: User terry not allowed to log in using too low UNIX UID 1000(terry) (see first_valid_uid in config file)" . Should i change the UID ?
