[New-bugs-announce] [issue44269] smtplib AUTH command doesn't handle EAI arguments

[John L]

New submission from John L <johnl at taugh.com>:

In an EAI (SMTPUTF8) mail session, AUTH usernames and passwords can be UTF-8, not just ASCII.

The fix is easy.  In smtplib.py, in three places in the auth() and auth_cram_md5() routines change ".encode('ascii')" to ".encode(self.command_encoding)"

I have tried this with EAI mail servers in India and China to be sure it works.
