Hello all, I have written a short function, based on a recipe in the Python Cookbook, that sends an e-mail. The function takes arguments that define who the e-mail is to, from, the subject, the body and an optional list of attachments.
The function works also perfectly, bar one slight problem. If you attempt to send an e-mail with just a body and no attachments, the receiving client still thinks that there is an attachment (so far tested in Mozilla Thunderbird and the Yahoo! webmail client). Although this clearly isn't a major problem, it is irritating and I am hoping to use my code at work. Obviously I can't be sending out badly formed e-mails to my clients. I can't for the life of me work out why. I have compared my code to every example that I can find in the Python documentation, on the archives of this newsgroup and of the Python Tutor list, and one or two random searches but can't see what is happening. Any advice or suggestions would be welcome.
