Add support for Cc: in django/core/mail.py

[tpetazzoni]

The attached patch adds support for Cc: in django/core/mail.py. Using the already existing 'headers' argument of the EmailMessage constructor is not enough, because just like Bcc addresses, Cc addresses must be passed to the RCPT TO command, so they must be present in the list returned by the recipients() method.

Patch that adds support for Cc

[Malcolm Tredinnick]

I've generally been -1 on this in the past. We're not aiming to implement all-singing, all-dancing email functionality here, since that already exists in the Python library.

You can send to anybody you like using the "to" line, or you can subclass EmailMessage to add CC functionality if you really want it (c.f. we needed to add Bcc because you can't use "to" for that). So this patch adds no functionality that isn't already possible, but adds more complexity to the code and the API.

Leaving open for a little while in case another core dev has a differing opinion.

No, I completely agree with Malcolm.
