Postfix configuration change

[bassplayer]

I install ISPconfig succesfully thanks.
my domain example.com
ISPconfig mc mc1.example.com
I use this machine as mail relay server of example.com to mail.example.com
In order to make it works I change manually /etc/postfix/local-host-names
I commented out example.com --> #example.com
it will tell postfix not to check local user when receiving email for this domain and directly relay it. it works find !!!

but this file /etc/postfix/local-host-names is back to original configuration, it happens 3 times already now. It happen again last friday.
On last friday I delete than add one website to ISPconfig, Is it causing the changes?,
During saving the configuration ISPconfig change the whole file or just append the new website.
If it change the whole file, so next time whenever I add/delete websites I need to check this file manually also.

Or is it can be done from inside ISPconfig configuration? thanks

Do not change /etc/postfix/local-host-names manually, ISPConfig will overwrite your changes. Instead you will have to set the website and co-domain to external mailserver in ISPConfig.

hi Till, Thanks for the tips.
this is what I do...
1. create example.com domain
2. update dns example com
mx record -> delete old one
create new point to mail.example.com

It Works! but when I try "host example.com"
it return "example.com has address (my ispconfig server IP)
no mx record.
Please let me know if it is the correct way!
I dont know what co-domain for! and how to set it up.
Regards,

If you want to see the MX record, the command is:

dig MX example.com
