apycot-moved #4046 avoid emails that are too big [deprecated]

If a project produces a lot of output (failing tests - for example hmm), a huge email can be generated (in this case 11M of text) and refused by the smtp.

It would be a good idea to have something that checks the size of the email, or the return code of the sending of the email to avoid waiting for the email to be sent. It could then send an email saying what went wrong.
