Thanks David, Here is some other tests I ran Issuing: - msg['Reply-To'] = '"foo Research Inc Foofoo BarBar on Summer Special Friday 050 days (2021-02-31" <catch...@foobar.exchange.com>' - msg['Reply-To'] = '"foo Research Inc Foofoo BarBar on Summer Special Friday 050 days 20210231 " <catch...@foobar.exchange.com>' But: msg['Reply-To'] = '"foo Research Inc Foofoo BarBar on Summer Special Friday 050 days 20210231 " <catch...@foobar.exchange.com>' worked. It looks more related to the length of the name than the character used. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44637> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
