New submission from Quae Quack <q...@daurnimator.com>:
smtplib.sendmsg is documented to take RFC822 addresses. and e.g. if the `to_addrs` argument isn't provided then it gets the To address directly from the headers (which is in RFC822 form). However it then proceeds to use it as an RFC821 address and sends it over the SMTP connection. https://github.com/python/cpython/blob/874809ea389e6434787e773a6054a08e0b81f734/Lib/smtplib.py#L542 ---------- components: Library (Lib) messages: 324653 nosy: Quae Quack priority: normal severity: normal status: open title: smtplib mixes RFC821 and RFC822 addresses type: security _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34591> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
