The comma always goes after the name in the beginning of a letter.
A comma is not required in the salutation of an editorial letter. You can use either a comma or a colon after the recipient's name. For example, "Dear Editor," or "Dear Editor:".
No, there is no comma between the month and the date in the heading of a letter. For example, "October 1, 2021" would not have a comma between October and 1 in the heading.
It is almost always a comma, but rarely I have seen a colon. When you are writing a formal letter, it is a comma, but if you were to write a informal letter to a friend, it doesn't really matter. For all of the letters I write I use a comma, and so does everybody else I know.
