Hallo!

Our company has decided to allow only SSL connections to the e-mailbox from outside. So I needed a SSL capable "imaplib.py" to run my mailwatcher-scripts from home.

Thanks to the socket.ssl() in recent Pythons it was nearly no problem to derive an IMAP4_SSL-class from the existing IMAP4-class in Python's standard library.

Maybe you want to look over the very small additions that were necessary to implement the IMAP-over-SSL-functionality and add it as a part of the next official "imaplib.py"?

Here's the context diff from the most recent CVS version (1.43). It works fine for me this way and it's only a few straight-forward lines of code.

Maybe I could contribute a bit to the Python project with this patch? Best regards
