hi,

yes. /etc/mail/sendmail.cf.

see this thread and remember to restart your sendmail services:

# /sbin/init.d/sendmail stop
# /sbin/init.d/sendmail start

Hi,

Be aware of that sendmail on HP-UX likes to resolve the domain that you are sending to.

If you behind a firewall with the sendmail server, the internal DNS not always resolves the internet domains.
Try to resolve (with nslookup) a domain that you like to send an email to from the server that runs sendmail. If this returns a IP address the sendmail sends the mail out to the configured relay-host.(see sendmail.cf in /etc/mail)

If you can not resolve the domain using a DNS server, try putting the internet domain in your local /etc/hosts file (fake IP-address while do the trick)

HTH,
Peter

Most of the time, you can relay through a smtp server

DS
[ip of relay server]

or hosthame

save sendmail.cf

/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start

Note that sendmail does NOT need to run as a daemon for mail to get off the box. Running it as a daemon for no reason is a bad idea.

You must configure:
- BIND ( Your Domain and Resolve method)
- SENDMAIL ( Your Domain, Relay server, etc )

You know how to ?
