What directory put the email-address-config-custom.xml file?

As far as I understood the question, it's about the directory to be used to save the email-address-config-custom.xml and in this case, the location pointed out in the 5th point is not the intended one as it is meant for holding the resource bundles. To the best of my knowledge, the 5th point as mentioned above talks about the path that should be used for resource bundles, that is the .properties file which holds key-value translation pairs.

I don't think the location to save the email-address-config-custom.xml is mentioned in the example, in fact, it is mentioned in the section 'Adding a Custom From Address' which is actually above the example.
