My two servers are nagios1.example.com and nagios2.example.com, They are both configured with local mail and smarthost.
On nagios1 in /etc/aliases
On nagios2 in /etc/aliases
So I'd expect executing this command on nagios1 would send a mail to nagios on nagios2:
echo 'test mail' | mailx firstname.lastname@example.org
Instead of this, exim call the remote smarthost router for delivery instead of doing the local delivery ( as nagios2.example.com is != nagios1.example.com maybe?).
I hope i've been clear enough. Tell me if any config file is needed.
edit: Adding nagios2.example.com to local_domains list could do the trick ? Looking for the right file to edit ..
Where the frack can I find local_domains settings all I found was
domainlist local_domains = MAIN_LOCAL_DOMAINS
/etc/exim4/conf.d/main/01_exim4-config_listmacrosdefs but ut appears to do nothing even with a restart of exim.
Found the right file : exim4.conf.template ( sigh.. ) , it's the file used when the config is not split in multiple files.
So I added nagios2.example.com to the local_domains list, result : nagios1 delivers the message to itself in /var/mail/mail ..
