Monitoring number of smtp bytes sent through python e-mail socket

[William Connery]

Hi,

I have a small python program with e-mail capabilities that I have
pieced together from code snippets found on the internet.

The program uses the smtplib module to successfully send an e-mail with
an attachment.

I want to give users an indication of the percentage of the e-mail that
has already been sent so as to avoid frustration when dealing with large
attachments or a slow smtp server. But the smtplib module doesn't seem
to provide access to the number of bytes that have already been sent.

Can anyone help, or provide a working example of sending an e-mail
attachment using basic python sockets whilst having access to the number
of bytes that have already been sent through the socket?

Many thanks.

William Connery
