Hi,

in response to a bug report I got the follow helpful comments from R. David Murray.
Many thanks to him. (Unfortunately, I don't know his email, so I can write him directly)

To generate an email (with non-ascii letters)

This works, but now I cannot add a date field

Trying

m['Date'] = datetime.datetime.utcnow().strftime('%m/%d/%Y %I:%M:%S %p')

I get

Traceback (most recent call last):

Many thanks for a hint,
Helmut.
