Re: lookup error for DNS query

It's more like a temporary DNS query issue.
Please make sure you have a working DNS server listed in /etc/resolv.conf and /var/spool/postfix/etc/resolv.conf (Postfix uses this one).


Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
