Thank you very much Gabriel, changing the NULL to None did the trick
(it also helps if I reload the changed module after editing!:( ). Yes
that is an old script and I will look into your suggestions. Basically
I'd just like to use the default mail client (windows or Unix/Linux)
to send simple mail with attachments, this way I can log the
attachments I send to a db for example for document transmittal/
register reports etc.
Thanks also for the code explanations,
Cheers,
Mick.
