Isn't "to mail", rather than "send an e-mail" another example?

I can accept that a verb minute comes from a noun directly, or to say that one is memoing comes from the noun memo, but mail? I have mailed things all my life. If ever the verb or noun was derived from the other both versions have been part of my life since I had vocabulary. I have always accepted mail to be one of those words that has various meanings, and various parts of speech. I don't think of the verb as being derived from the noun.
