Internet mail config. for hp-ux

[Jesus Alonso]

I need to change the config file on my hp-ux system on wich the ip address of my internet mail computer is.
thanks.

That is usually in /etc/hosts. It is common to have this as an alias:

192.168.201.116 foo foo.com www.foo.com mail

Even if my internet mail computer is a windows 2000 server?

The answer depends on how you resolve hostnames.

If /etc/nsswitch.conf has files first, the above answer is correct.

If you use name resolution, as in nsswitch.conf is dns for first try, you need to have an entry for the Internet mail computer entered into the DNS database.

Try this as root on hp-ux

nsslookup name_of_internet_mail_computer

for example

nslookup mail.yourdoman.net

If the answer looks like this:

nslookup mail.yourdoman.net
Name Server: name.yourdomain.net
Address: 10.1.10.99

Trying DNS

Then you are using names resolution.

if it says FILES first, then you are using files first and post one is good for you.

nsswitch.conf is commonly set up to fail over to FILES if DNS doesn't work so putting it in /etc/hosts should be good enough, but you'll have to look at the nsswitch.conf file to be sure.

it is not a problem of name resolution, i need to update (because my w2k internet mail server changed name and ip address) on my hpux server wich internet mail server must recive the elm mails generated on the hpux server.

See if the hp-ux machine has an /etc/mail/sendmail.cf file with a line starting with DS.

E.G.
DSold.server.com

If so, change it to
DSnew.server.com

and re-start sendmail. That should cause all of the mail to be relayed via new.server.com where it used to be relayed via old.server.com.

[Paul Sperry · Accepted solution]

in /etc/mail/sendmail.cf there should be a line like


# "Smart" relay host (may be null)
DS

change it to

DS

Kill sendmail:

ps -ef | grep sendmail
(not the pid#)
kill pid#

Start sendmail:
sendmail ???bi
sendmail ???bd

Doesn't matter what kind of box relays the mail. Windows 2000 usually relays mail with Exchange, and it does not allow relay out of the box.

The exchange admin will have to explicitly authorize it.
