sendmail relay and GroupWise mail server

[hubbell]

I have a hp-ux B.10.20 machine which has no internet access, and a GroupWise mail server.

Now I hope to send email to an internet email account on my hp machine, so I try setting my GroupWise mail server as the relay for my hp using the DS macro in sendmail.cf and adding the GroupWise mail server into my hosts file in hp. This works fine as long as the receipant is a user of GroupWise mail server. But when I tried sending to a email account outside my company, it shows "service unavailable". Here's the sample.

1. Send mail to a user in GroupWise.

#date|/usr/sbin/sendmail -v iamuser@mycorp.com

iamuser@mycorp.com... Connecting to [172.16.148.4] via relay...

iamuser@mycorp.com... Sent (2.0.0 Message received OK)
Closing connection to [172.16.148.4]
>>> QUIT
221 2.0.0 mycorp.com closing

This action is successful. Try again sending to my hotmail.com account, it failed.

#date|/usr/sbin/sendmail -v iamuser@hotmail.com

I suppose after setting the GroupWise as relay for my hp, all emails from hp and sending to receipants outside localhost will be relayed to my GroupWise mail server and let it handle the rest. But I don't know why the GroupWise server only recognizes the local domain. Actually I can send email to any valid email account from my PC via this mail server.

I am also pretty confused about the error message. It says &quot;501 5.7.1 This system is not configured to relay mail from <root@picon03x.mycorp.com> to <iamuser@hotmail.com> for 172.16.65.42
iamuser@hotmail.com... Service unavailable&quot;. Which system is not configured, hp or GroupWise?

Thanks in advance for any suggestions.

It sounds like relaying is turned off in GroupWise so it will send mail for the local domain, but no outside domains. In NWAdmin, go to the GroupWise view and the details of the GWIA. Under the Access Control section, there is an SMTP Relay button. Check to make sure relaying is turned on, BUT once you do, it also allows others (spammers) to use your system as a relay for their junk mail.
