During the history of the city of Calais, there have been three post offices.
Briefly, the history of these three is as follows:
1. Schoodick Falls post office was established on 12 February 1807 an was renamed on 1 July 1809 as Calais post office, which is still operating.
2. Milltown post office opened on 10 February 1827, closed on 11 April 1835, and re-opened on 24 April 1837. On 31 December 1909, Milltown post office was renamed as Milltown Sta. Calais and is still operating.
3. Red Beach post office was established on 5 March 1850, was renamed on 12 February 1965 as Red Beach Ind. Rur. Sta. Robbinston. However, a card of 13 February 1965 shown below is marked “First Day–, but it still bears the earlier Red Beach postmark. This post office closed on 6 July 1984.
