I don't recommend to stop sendmail daemon. Some system events (eg. EMS) send mails to root.
Look at configuring your application not to send mails.

Hi there

If you are sending mails to root@localhost, aren't these going to the root mail account on the Unix server instead of being sent/relayed?

Hi keith,

Yes it is. Any idea how can I keep those mails in queue send to other than localhost?? since root@localhost is working EMS won't have any problems.

At the moment I modified DS macro to non existing host, so mails remain in queue as hostname lookup failure.

Any good way of doing it??

One way u can add the entry
'root: /path-to-file' in aliases database so the mails for root is appended to that file instead of sending to its actual mailbox. For reading these mails u can simply append this file to ur mailbox file.

tools:

sendmail -v -q

This will process the queue in verbose mode and give you a clue why the mail is not moving.

Most common cuases:

1) Bad host resolution. For full internet resolution you need to set /etc/nsswitch.conf to dns and make sure the machine gets valid host resolution answers from the name servers in /etc/resolv.conf

2) Relay issues. To avoid host resolution issues, many set the DS directive in sendmail.cf If you do that you must restart the sendmail daemon:

/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start

The DS directive must point to a valid sendmail server that permits, explicity the host with the DS directive to relay mail.

The error message from the sendmail -v -q command will be instructive as to what the next step should be.

The impression I am getting here chaps is that Neil wants the mailq to hold onto certain emails (don't deliver, but hold) but carry on processing others.

Thanks stev for your reply,I believe keith understood my requirement 50%.I want to hold mails send to user@anydomain in queue while delivering user@localhost.

I could achieve this by modifying DS(smart relay)macro to unknown host, Which keeps all mails to queue.

I am not happy with my solution, any good thoughts??
