Signing off letters

Hi - I understand that normally one would finish a letter addressed to, 'Mr or Mrs X' as 'Yours sincerely', and a letter addressed to 'Dear Sir' as 'Yours faithfully', but what if one is writing to a magazine or newspaper, and starting 'Dear Editor' - I would imagine this should finish 'Yours sincerely' as the letter gives a title rather than just Dear Sir - Is this correct?

If writing to a newspaper, the British way is as follows:

Sir, (no Dear and it seems that Sir is used if the editor is a woman)


Yours faithfully (though many letters use sincerely)
