exim4 cannot send email to root (all localhost users)
I have a problem with exim4 configuration. I try to send email to root, but email stay frozen in queue.
I tried this:
root@server2:~# echo TEST | mail -s "Hello this is testing email" root
and email is in queue (frozen), please see some outputs below.
In log (/var/log/exim4/mainlog) is this message:
2014-06-11 11:47:36 1Wuf84-0004o3-E4 <= [email protected] U=root P=local S=416
2014-06-11 11:47:36 1Wuf84-0004o3-E4 remote host address is the local host: server2.mydomain.cz
2014-06-11 11:47:36 1Wuf84-0004o3-E4 == [email protected] R=dnslookup defer (-1): **remote host address is the local host**
2014-06-11 11:47:36 1Wuf84-0004o3-E4 Frozen
Local host is routable (I hope):
root@server2:~# exim -bt localhost
LOG: MAIN
remote host address is the local host: server2.danielblazek.cz (while routing <[email protected]>)
[email protected] cannot be resolved at this time: remote host address is the local host
root@server2:~#
Configuration of hostname is right:
root@server2:~# hostname && hostname -f
server2
server2.mydomain.cz
Aliases seems to be OK:
root@server2:~# cat /etc/aliases
# /etc/aliases
mailer-daemon: postmaster
postmaster: root
nobody: root
hostmaster: root
usenet: root
news: root
webmaster: root
www: root
ftp: root
abuse: root
noc: root
security: root
root: root
clamav: root
Do have any idea how can I fix it? With Postfix I never have problem like that. System emails always was delivered to /var/mail folder. But with exim4 I' m on the rocks. It's required for me receive system emails...
Please ask me if you need more information or outputs. Thank you for all replies!

Answer
remote host address is the local host is an exim error message which indicates that the sender or recipient's domain has your machine's hostname/IP, but exim is not configured to accept mail for that domain.
Exim has a standard domainlist named +local_domains that pretty much every different exim configuration system uses. See what domains are configured for your system by running:
exim -bP '+local_domains'
You will probably see a command that looks up a list of domains from a file. Put your hostname (in this case, it looks like it's an implicit hostname "localhost") in that file and exim should begin to work properly. Your test was slightly incorrect; you must pass the username you are delivering to, not the hostname:
exim -bt root
