I followed this tutorial to install a LAMP with webmin/virtualmin. I use yum to install postfix. Everything used to work very fine until today. I now have this below error when trying to create virtual server in virtualmin:
Failed to create virtual server : No virtual domains file (virtual_alias_maps) was found in your Postfix configuration!
This obviously has something to do with the configuration of my installed postfix. I wonder how to fix this problem? virtual_alias_maps?? have no idea about it.
appreciate your help.
