One more data point. An attachment of 500-600kB was ok, but an attachment
of 1.5MB was not.

For the 1.5MB file case, the memory errors just kept coming until the .bak
file was left in place, and not moved away. Does this point to the mail
just being too big for python?

With the larger 1.5MB file:
