  server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
  server.login(gmail_user, gmail_password)
  server.sendmail(mail_from, mail_to, mail_message)
  print(mail_to)
server.close()

Answer 1

Send_to 必须是一个字符串 object，地址用“,”分隔。

例子：

send_to='xyz1@gmail.com,hhdasn@yahoo.com'

Answer 2

执行 email 发送的行是server.sendmail(mail_from, mail_to, mail_message) 。 你叫它一次。 您可以通过在它旁边放置print(mail_to)语句来检查它。

如果要多次发送 email，则需要循环调用sendmail 。
