Can't send system emails
First of all, this is my first post here, so hello to everybody who reads me :)
I've just installed a Zimbra OS version on a CentOS 5.5 machine, and I have a little problem.
I can send emails perfectly to example.com and external domains from any account I've created, but there are some emails that i can't send. What I'm trying to do is simple, just in a terminal:
echo “This was a test” | sendmail -f email@example.com root
This generates a response to firstname.lastname@example.org that says:
<email@example.com>: mail for server2.example.com loops back to myself
The problem is that root account points to firstname.lastname@example.org instead email@example.com
My configuration looks like this:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
220.127.116.11 server2.example.com server2
dig example.com mx
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> example.com mx

The server that has installed Zimbra is the only that can send this emails to root, the rest of the servers i have send this ones normally.
This server only have one domain: example.com
Anyone have an idea of what is happening here? All comments are welcome and apreciated.
