Of course, attached is a straightforward translation of the original. As
you can see it only requires very minimal changes from the original
Python.

1. Numbers are doubles by default in Octave as we all know, so you have
   to force the port to be a Python integer. Casting to an Octave int
   type will also work.

2. Octave doesn't have a syntax for multi-line strings like Python does,
   so I wrote the small example message body here with newline esacpes.
   For a longer multi-line string, one could use a cell array and the
   strjoin function.

3. The Python `with` statement is syntactic sugar, Octave doesn't have a
   syntax for declaring a local variable that will be destroyed
   automatically after a block scope is finished.

4. The `pyargs` function is required for passing keyword arguments to a
   Python function in the form that it expects.

That's it, attached example works for me with a suitable server, sender,
recipient, and password filled in.

Thank you for bringing this to my attention, I would like to include a
version of this script as an example in the package. Do you have an
original citation for the Python script? URL, author, license?

Keep the questions and examples coming!
