Hi,
Command host does not check /etc/hosts file. Is it a bug or normal behavior?
My sendmail could not deliver mail to localhost. I had to comment the
following lines in the config file.
# Resolve map (to check if a host exists in check_mail)
#Kresolve host -a<OKR> -T<TEMP>
#C{ResOk}OKR
My system:
uname -a
FreeBSD fb.homeunix.org 4.7-STABLE FreeBSD 4.7-STABLE #1: Tue Dec 31
21:29:27 MST 2002 bkn@fb.homeunix.org:/usr/obj/usr/src/sys/BSD i386
I did some investigation:
