Just a couple of fixes to improve the performance.
The self._ip_address_cache was not actually being used.
The get_reverse_dns call was not passing on the cache parameter that get_ip_address_info receives.
The cache was being considered to be undefined because it was empty, so entries were not being added to make it not empty.
The dns_timeout was not being passed all of the way from the options, resulting in 6.0 seconds always being used for mail messages. (I consider setting the timeout to 2.0 seconds to be a performance improvement.)
I also made the update to the Dockerfile to work with the new source folder structure.
