Miko Ohtamaa added the comment: I think there is something more in this.
I am running Python 3.5.0 (default, Apr 24 2016, 12:47:36). Sparkpost servers require AUTH LOGIN approach as per their instructions https://support.sparkpost.com/customer/portal/articles/1988470-smtp-connection-problems When trying to use these (free) servers smtplib authentication will result to smtplib.SMTPAuthenticationError: (500, b'5.5.2 unrecognized command') like in the issue description earlier. I am still investigating this. ---------- nosy: +miohtama, ned.deily _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25446> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
