In a standard DA configuration, SMTP-AUTH and POP-before_SMTP are both set up, and exim won't relay.

If you're using SpamBlocker make sure that no domains on the server are listed in the /etc/virtual/whitelist_domains file, as thats the only known hole.

if it have only one ip in white list, this is the cause to smtp problem?

So, this is a bug. it will delete one ip in my white list and test it again.

Thank you Jeff.

I have deleted in whitelist already but the problem still not resolve.

I can use any email to send from my server.

Reinstall your exim.conf file.

What does this mean?

"User 0 set for local_delivery transport is on the never_users list"

Thank you

 

[smtalk]

"user 0" = "root"

This line in exim.con tells exim that if it is being sent to root - reject the email:

never_users = root

If you want - you can remove the line from exim.conf and restart the service, everything should be fine then.
