Does Exim know about variables custom file?

[Richard G]

I was just having a look around and then I've seen this in the /etc/exim.conf file:

.include /etc/exim.variables.conf
.include /etc/exim.strings.conf
.include_if_exists /etc/exim.strings.conf.custom

and I found:

  .include_if_exists /etc/exim.check_mime.conf.custom
  .include_if_exists /etc/exim.easy_spam_fighter/check_mime.conf

Looks good to me except for one thing.
In the /etc/exim.variables.conf it says:

#Do not edit this file directly
#edit /etc/exim.variables.conf.custom

But how does Exim that this file must be loaded? I don't see a line anywhere like:

.include_if_exists /etc/exim.variables.conf.custom

So since I can't find this line anywhere, just out of curiosity, how does Exim know that this custom file should be loaded?

./build exim_conf handles it.

But build exim_conf only builds the exim.conf which does not mention this custom file but does mention the other custom files.

That is what I don't understand.
Could you explain a bit more how Exim knows about this file hence it's not in the exim.conf?

 

[smtalk]

No, it also takes care of /etc/exim.variables.conf and other configuration files of exim Exim does not know anything about /etc/exim.variables.conf.custom, as it only reads /etc/exim.variables.conf, and CB takes care of /etc/exim.variables.conf (so that it'd have your custom values).

Oooh like that. I was just wondering because this was the only *.custom file I missed in the exim.conf file.
But I knew it worked, only not how.

Thank you for enlightening me.
