Checking relay mail server

C_V — Mon, 29 Dec 2008 13:14:58 GMT

Hi guys im not good in sendmail hope you can help me.

i tried to send a test email from one of our server echo "test email" | sendmail -v email address. and as i review the output it says that the email was successfully delivered the mail, so i guess there is no problem with the servers mail system.

however the test email was not received, is there a way to check if the relay server has sent the email.

i check the network connection between the server and relay server and its fine.

How i check if there is something wrong with the relay server?

Have you looked at /var/adm/syslog/mail.log?

sendmail -bp says that the mail queue is empty.

As per mail.log the mail was accepted for delivery.

Was that to the target machine or a relay? Can you look at that machine's mail.log to see what it did with the message?

Try sending a test message with sendmail -v. This will provide some additional details:

sendmail -v bill@bill.com < /etc/profile

If the message is accepted by the server, then your HP-UX sendmail is configured OK. So you'll have to check the mail server to what is has done to your mail. It may be rejected internally and simply not returned back to your server.

Yes the test mails i sent was accepted and was delivered, but how do i check the mail server to know if it really delivered the mail.

Send it to yourself on that server?
Why would it get to the mail server and not be delivered?

Thats what to know if the mail server really delivers the mail, is there a log on the server that can verify if the mail was really sent?

So far you told us that your-server sends email successfully to the mail-relay server. What kind of server/OS is the mail-relay server and do you have access to it? There could be further mail relay and delivery after the first mail-relay server. Who is the final receipient and at what server?

Are we talking about the mail server, where the mail ends up? Or a relay server, where it is forwarded?
There should be a log on both. But it may be forwarded multiple times.
So you need to test it once and then assume it works.
