"POSTSPERRE"

Cut off from the city, the ghetto's population began using the post office primarily to contact friends and request food parcels. Above all, they contacted their neighbors in Lodz. This took such a massive turn that on June 3, 1940, the German authorities banned the sending of parcels from the city, encouraging people to send the equivalent of the products in cash, deposited in a special ghetto account in the city's cash register. Food parcels could be sent from abroad, which was understood to include the General Government. 

In mid-July 1940, the first mail ban, referred to in the ghetto as “Postsperra,” was introduced. It was justified by sanitary requirements, namely the outbreak of dysentery.
