It was a free service without any extra charge. One had to write Q. M.S. on top of the envelope, inland letter or a post card.
However, after the introduction of the Speed Post Service for which one has to pay extra charges, the Q. M.S. service is no more in use.

QMS-Quick Mail Service- was existing before the introduction of Sped post and coming of couriers.
Generally postal mail articles were dispatched to distant places by railway and public transport bus service. Such vehicles carried a board or painting like RMS-Railway Mail Service or just' Mail'. Earlier trains were also named Madras Mail,Bombay Mail etc. For a local or an accessible geographical area there were postal department's mail vans. (For overseas mail also there were Air Mail and sea mail.These were charged differently.)
However subsequently postal mail articles were also(additionally) sent by air from and to main cities having airports. There was no separate Air Mail unlike overseas mail. For example if one has to send a letter from Chennai to Mumbai, some articles which got sorted and readied within a particular time slot were sent by air. Those which came later or at other time slots were sent by railway,as usual. People came to know this. Postal department also allowed people to write QMS on the urgent letters so that such letters were sorted and sent by the immediately available air dispatch slot.
I have experienced that I used to get a 'QMS' written letter from my native place to Mumbai, within three days, whereas other letters came after five days. However as the QMS was just a contextual goodwill free facility and no record is kept nor receipt given, no one could legally or rightfully claim on that.
However when people started writing QMS in every letter, the priority got lost in the crowd and postal department stuck to the time slots. Subsequently private couriers came into the scene and Speed post also got implemented QMS lost its significance and usage.
Caution: Explosive. Handle with care.
