Unable to send emails using mail command


Hello everyone,


I currently have a Debian Etch server configured and running. I was able to send emails using the mail command before. However as of today I'm not able to do so. I tried starting the /etc/init.d/sendmail script but I wasn't able to locate the service script or the config script either.

I have checked the system to see if it has working email server and was able to connect with out any problems. (telnet 127.0.0.1 25)

Any suggestions why I'm still not able to send emails using the mail command?

What do your mail logs show (/var/log/maillog) ?

I check the the /var/log directory and the following directories were empty mail.err mail.info mail.log mail.warn


Though I'm not sure why the daemon script(/etc/init.d/sendmail is not present in the system).


I appreciate your help.
Thanks!

I don't know what startup scripts debian uses to startup exim's daemons. Perhaps it is /etc/init.d/exim or some variant.

What happens when you try to send mail ?

[ ps. my netstat command had a typo - the arguments should have been -aln ]

Your mail logs should be in /var/log/exim4. What are they saying? Need to check how exim is configured. Have a look into the /etc/exim.conf file.

So now the question is, can you telnet to port 25 of that address:

telnet 74.52.84.210 25

I mistype the hostname. It should be trinetsolutions.com not trinesolutions.com. I can't telnet to that host on port 25 because their is not mail server running on it (connection refused as well).

I removed the mail queue and restarted the exim 4 daemon and was able to send emails to different address successfully. But I still not able to send mail to any address in the trinetsolutions.com domain. Email header indicates that the hostname is unreachable. (DNS )

Use the logs as your source of diagnostics, not the bounced mail message.

I see trinetsolutions.com mail is handled by:

Code:
$ host trinetsolutions.com 
trinetsolutions.com has address 216.177.75.66
trinetsolutions.com mail is handled by 30 aspmx2.googlemail.com.
trinetsolutions.com mail is handled by 30 aspmx3.googlemail.com.
trinetsolutions.com mail is handled by 30 aspmx4.googlemail.com.
trinetsolutions.com mail is handled by 30 aspmx5.googlemail.com.
trinetsolutions.com mail is handled by 10 aspmx.l.google.com.
trinetsolutions.com mail is handled by 20 alt1.aspmx.l.google.com.
trinetsolutions.com mail is handled by 20 alt2.aspmx.l.google.com.
So you'd have to telnet to one of the listed MX servers, not the trinetsolutions.com IP address shown.

Smile Issue Solve

It turned out the reason why exim wasn't able to email messages to the trinetsolutions.com domain is because the email server is configured to be part as a subdomain of it. This causes exim to get confused and found any address sent to that domain unreachable.


I appreciate you help Mr. C!!!

This command verified this:
exim -d -bt user@mydomain.com
