Re: Configure mail Alert

Hi. If you want to send messages from this server to others, forward it to smarthost, then you could modify /etc/sendmail.cf file and add the DS directive (around line 720) -

# "Smart" relay host (may be null)
DSsmarthost.company.com

Just add your smarthost/relay IP or hostname (check if it resolves first) after DS (no spaces between), restart sendmail and that should do it.

What will be our next step?

Check the sendmail logs to see what happens when you send an email.

Talk to your exchange administrator and check if the exchange server allows SMTP relaying from your server.

You could also try using sendmail with the -v switch. It might give some clues as well.

Re: Configure mail Alert

Hi Mahbub,

most likely your Exchange server isn't accepting to relay mail from your HP-UX host.

You should look at your HP-UX host's /var/adm/syslog/mail.log if mails you sent from this host are accepted by the remote relay's MTA (viz. your domain's Exchange server).
If so you will usually find an entry like "queued as ..." (where the ellipses stand for a message id under which the remote relay put it into its mail queue).
Or a successful entry may read like "queued for delivery" or similar.
If on the other hand the remote relay rejected mails from your host it often will say so by an entry like, "reject=550 ... Relaying denied".

You could also try to talk to the remote relay directly.
The simplest way would be to talk plain SMTP over a telnet session.

Open a telnet client from your HP-UX host to the hostname or IP address of your Exchange server on port 25.

Then use the SMTP commands, helo, mail from, rcpt to, data, ".", quit

But if the Exchange server rejects mails from your host it will probably already tell so once it received the "helo" command along with your host's domain as argument or a "mail from" an unsuitable sender.

Then you need to talk to the postmaster of your Exchange Server and ask them to configure their MTA to accept mails from your HP-UX host.

I would verify that the billings email id/alias exist with the mail admin.

What happens when you email to your own email id or a known to work id?

This is a DMZ or firewall issue I bet.

Re: Configure mail Alert

Probably you cannot reach the mail exchanger for domain mtn.com.af. directly.
But you hand it over to your smarthost you configured anyway.
I assume that your smarthost is rejecting it because it hasn't got a proper return address that it can advertise (in the envelope) to the mail's recipient in the Internet (for bounces or replies).

What does your intranet DNS resolve from your hpux host as mail exchangers for the mail's recipient domain?

e.g.
$ nslookup -q=mx mtn.com.af.

You could also try what your hpux host's sendmail makes of this

$ /usr/sbin/sendmail -bv billing-support@mtn.com.af

Anyway, I would contact your smarthost's postmaster and ask what needs to be configured and what the prerequisites are.
