There are 4 servers which all use the same mail server in the cluster.
web1 – mail server/web server
web2 – mail server/webserver
db1 – db server
db2 – db server
When db1 & db2 cpbackup is complete, the email is sent out but never received by the admin and fails with the message

Server replied: 550 No Such User Here

From the exim_main log;
2009-11-19 06:07:26 [15704] 1NB4rG-00045H-LL ** [email protected] F= R=virtual_aliases: No Such User Here

When checking exim -bt and whm mail troubleshooter, we get the error; “virtual_aliases router forced address failure”

The error in this case was resolved by removing the “” for web1 and web2 from the /etc/localdomains.

This allowed the mail to resolve correctly to the mail servers and be sent out to the admin from db1 & db2.

[[email protected]] ~ >> mail -s “test” [email protected] (hit enter) type in message,
test from db2
hit enter for new line, when finished with message, hit CTRL+D Cc: will come up, type in second email address if you would like and then hit enter again to sent the email
Cc: [email protected]
The message has now been sent or should be;

2009-11-19 06:24:14 [17647] cwd=/root 4 args: send-mail -i [email protected] [email protected]

I hope this makes sense and is able to help someone out…
