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  1NB4rG-00045H-LL ** email@example.com F=
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 “domain.com” 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.
[firstname.lastname@example.org] ~ >> mail -s “test” email@example.com (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
The message has now been sent or should be;
2009-11-19 06:24:14  cwd=/root 4 args: send-mail -i firstname.lastname@example.org email@example.com

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