I've already had to add code to "normalize" addresses with dots and plusses. That should've been my first sign to move to a different design.

Not all providers tread dots and plusses the same. Gmail ignores dots (strips them out), and omits a plus and anything after it. Some providers include dots, so stripping them will be a different email address. Same for plusses and the content after them.
