Because East Boothbay is not its own town, I think it is better to mark East Boothbay addresses as "Boothbay" since it is a part of that town. This will be consistent with the similar "West Boothbay Harbor" situation, where it has its own zip code (04575) but is still a part of the town of Boothbay Harbor. The addresses there are marked as "Boothbay Harbor, 04575" so I think it makes the most sense to mark East Boothbay addresses as "Boothbay, 04544".
