I now have my sendmail up and running. Thanks to all who helped. I decided
to scrap it and start again - I installed the 8.10.0 tarball, and worked on
it line-by-line until it made some sort of sense to me. Sendmail is now
sending mail fine, and fetchmail is running in daemon mode to check for mail
regularly. WOOHOO.
I am, however, still having some DNS problems it looks like. I for some
reason cannot do reverse lookups any longer. I don't remember having
difficulties with this before, seems I have screwed something up lately.
This is my named.conf file:
options {
directory "/var/named";
forwarders {
203.2.75.132;
203.2.75.108;
};
};
zone "." {
type hint;
file "named.ca";
};
zone "0.0.127.in-addr.arpa" {
type master;
file "0.0.127";
};
zone "quark-au.com.local" {
type master;
file "quark-au.com.local";
};
zone "100.168.192.in-addr.arpa" {
type master;
file "100.168.192";
};
-=-=-=-=-=-=-=-=
This is my 0.0.127 file:
; /var/named/0.0.127
; for quark-au.com.local
;
@ IN SOA galahad.quark-au.com.local. root.quark-au.com.local. (
2000041001; serial
10840; refresh
3600; retry
604800; expire
86400; default_ttl
)
IN NS localhost.
1 IN PTR localhost.
Are these files any help to those who know more than I - I have looked at
this for too long, and something obvious is being overlooked.
Regards,
Hilton Travis
