The MLE entered production in 1895, and ceased production in 1907, when the SMLE was introduced. Most countries manufacturing SMLE rifles ceased after 1945, as they had a glut of surplus rifles following the war, but some countries continued making them. The last country to mass produce the .303 calibre rifles was India, with their production ceasing ~1960.
".303 British" is usually used to denote a caliber, as opposed to a specific firearm. Perhaps the most famous rifle in that caliber was the SMLE, which is the abbreviation for Short, Magazine, Lee Enfield.

They were made from prior to WW I, and continued through the Commonwealth nations (and former Commonwealth nations) into about the 1960s. So, yes, the caliber .303 British and the Enfield name are linked- but Enfield is not the full name of the rifles and carbines. Run a Wikipedia search on SMLE for some more reading.
