I’ve always noticed this and thought it was a bug ore something.
But this week i’ve updated to Mavericks and now the number of sending emails in the message is up to 20.
I simply create one new email and send it – than at the bottom left i see: Sending: 20 of 20
Anyone knows where this comes from?
Just figured out the number it says is the total of emails i’ve send this day, of all my email accounts together.
that’s kind of stupid..
