Re: Configure sendmail using DNS???
/etc/resolv.conf
/etc/nsswitch.conf
/etc/mail/sendmail.cw
resolv.conf will have the domain name for your network, while nsswitch.conf specifies how to resolve names and sendmail.cw defines the names that your local system might be called. resplv.conf and nsswitch.conf are required for normal DNS such as telnet and sendmail.
For resolv.conf, the format is something like this:
domain mydomain.com
nameserver 12.34.56.78
nameserver 23.45.67.89
Use this for nsswitch.conf:
passwd: files
group: files
hosts: files [NOTFOUND=continue UNAVAIL=continue] dns
ipnodes: files [NOTFOUND=continue] dns
services: files
networks: files
protocols: files
rpc: files
publickey: files
netgroup: files
automount: files
aliases: files

Re: Configure sendmail using DNS???
what happens if you nslookup
if you do not get a successfull response then either your resolv.conf is wrong or there is no entry for this host your main DNS server.
fix that and you should be good to go.
(you do need to ask the mail admin to allow your mail forwarding, ya ,know )

Re: Configure sendmail using DNS???
In a Corporate environment DNS setup requires that port 25 be open to the public Internet to deliver mail to the domains. This port is almost never open.
Though if your requirement is to only deliver within the Corporate envionment the DNS style setup might work.
In general, HP-UX servers are configured to relay to a smtp or Exchange relay server.
