Primero encontré el siguiente error:

UnicodeEncodeError: 'ascii' codec can't encode characters in position 9-11: ordinal not in range(128)
Cuando encuentre este error, modifique inmediatamente command_encoding en la pila de errores anterior, de la siguiente manera:
def send(self, s):
"""Send `s' to the server."""
if self.debuglevel > 0:
self._print_debug('send:', repr(s))
if self.sock:
if isinstance(s, str):
# send is used by the 'data' command, where command_encoding
# should not be used, but 'data' needs to convert the string to
# binary itself anyway, so that's not a problem.
s = s.encode(self.command_encoding)
sys.audit("smtplib.send", self, s)
Como se muestra arriba, modifique self.command_encoding en el archivo smtplib.py y cámbielo directamente a 'utf8'. Después de la modificación, reinicie el proyecto y se informará el siguiente error:

Luego vaya al archivo Policy.py y modifique la siguiente información.
folded = self._fold(name, value, refold_binary=self.cte_type=='7bit')
charset = 'utf8' if self.utf8 else 'ascii'
return folded.encode(charset, 'surrogateescape')
En el archivo Policy.py con el problema anterior, modifique la parte del conjunto de caracteres como se indica arriba y elimine charset = 'utf8' if self.utf8 else 'ascii'la parte, y luego estará bien. Es realmente molesto que no pueda encontrar la respuesta que quiero en varios Baidu. Grábalo.
