Sendmail: Sending outgoing test message in verbose/debug mode
As root you may send a test message in verbose mode.
You should get full transcript of SMTP session to the remote SMTP server.
(echo: subject: test; echo) | /usr/sbin/sendmail -v -Am -i [email protected]
You may add additional debug/tracking command line options:
-d8.20

I am getting alot of the following messages from an ISP when sending out emails. Is there any way to get more information from these ? Users are reporting that they are not receiving any emails?
Jul 5 17:02:50 smtp sendmail[11239]: r6592of7011232: to=, delay=00:00:00, xdelay=00:00:00, mailer=esmtp, pri=168781, relay=mx12.example.com.com. [123.123.123.132], dsn=5.0.0, stat=Service unavailable
Is it possible to start running debug mode for sendmail?

Jenny D almost 11 yearsThe way to get more information is to contact that ISP. In theory, the address
[email protected]
should get an email to the person in charge of email systems, but there's the problem of theory and practice again...

Vivek Kodira over 9 yearsI have the same problem and running in verbose mode did not help debug the issue further. The verbose logs actually indicated that the mail was sent. maillog mentions otherwise (stat: Service unavailable)
