Late resolution for POSTMAN_PARAMS_EMAIL and POSTMAN_FROM_EMAIL

[Meiyer]

I think that cluttering my settings.py with code that customizes Postman’s behaviour is not very nice. I prefer all customizations to Postman (including the views, forms, etc.) to be in a dedicated app. For this to work, the two mentioned settings should support a string in the form ‘app_name.module_name.function_name’.

The support of 'a.m.f' syntax can be added to these two settings.

The implementation of this feature for others settings relies on the detection of a '.' character in the string. This is not enough for POSTMAN_FROM_EMAIL, which likely contains that character. I propose the absence of '@' as an additional criteria.
