Sendmail on HP11.23 -- no outbound

[Joe Bozen]

We've been running sendmail on our HPUX 11.23 for a couple of months. All of the emails have been processing because they are a part of our domain. We are now attempting to send emails to people who are not a part of our domain (someone@hotmail.com) All of those email end up as being deferred on the mailq. I am using the basic sendmail and have not really touched anything so I'm pretty sure that I just don't have anything really setup. I guessing my UNIX server has to pass this on to some other mail exchange to process, right? Maybe our groupwise service?
MAILQ EXAMPLE
# mailq
/var/spool/mqueue (4 requests)
----Q-ID---- --Size-- -----Q-Time----- ------------Sender/Recipient------------

(Deferred: Connection timed out with mailin-02.mx.aol.com.)

If you want to pass on to the Groupwise server, then you need to set the DS macro in sendmail.cf to that server:

DSgroupserver.yourdomain.com

You may also have to set masquerading:

DMyourdomain.com

I tried the DS... but I got this error:

>>> RCPT To:
550 Relaying denied

The inhouse email still works. I used the server name (ie myservername.my.domain) as the DS host that was reported back from my successful sendmail -v command.

250-myservername.my.domain
250-8BITMIME
250-SIZE
250-DSN
250-AUTH LOGIN
250 AUTH=LOGIN

Hi,

Looks like your relay server is denying to relay email from within the domain to the outside world. Check with the mail admins or the primary admins who manage the mail relay server.

Hope this helps.

Several ways to solve this:

1) Make sure your machine can resolve outside hostnames. That means setting up /etc/resolv.conf to point to dns nameservers that can actually get you the ip address of servers such as mailin-02.mx.aol.com

2) Set up relay to a valid server that will handle your mail. This should be an internal machine that is explicitly allows the hp 11.23 machine to relay mail. The directive DShostname_of_relay must be set up.

Example:

DSmailrelay.your.net

or

DS
[192.168.0.4]
# ip address of the relay server.

Save the /etc/mail/sendmail.cf file

/sbin/intit.d/sendmail stop
/sbin/intit.d/sendmail start

Diagnostics:

sendmail -v -d8.99 -d38.99 Gina8184@aol.com

type some text

.


# this gives full diagnostics.

also:

sendmail -v -q

Same basic function.

Remember if you choose DS relay you must explicitly set up the relay server to allow relay from your internal hp-ux 11.23 machine.

Your Groupwise admin should be able to configure Groupwise so that it will accept and relay mail from your HP-UX host. Our Groupwise is configured that way so it can be done.
