使用Python smtplib发送邮件时权限被拒绝错误

Question

我正在尝试用Python 3.2发送邮件。我的代码如下：

#from email import Encoders
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.utils import COMMASPACE, formatdate
import os
import smtplib
from base64 import encode
from email import encoders

def sendMail(to, subject, text, files=[],server="smtp.mydomain.com"):
    assert type(to)==list
    assert type(files)==list
    fro = "From <myemail@mydomain.com>"

    msg = MIMEMultipart()
    msg['From'] = fro
    msg['To'] = COMMASPACE.join(to)
    msg['Date'] = formatdate(localtime=True)
    msg['Subject'] = subject

    msg.attach( MIMEText(text) )

    for file in files:
        part = MIMEBase('application', "octet-stream")
        part.set_payload( open(file,"rb").read() )
        encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment; filename="%s"'
                       % os.path.basename(file))
        msg.attach(part)

    smtp = smtplib.SMTP_SSL(server, 465)
    smtp.ehlo()
    smtp.set_debuglevel(1)
    smtp.ehlo()
    smtp.login("myemail@mydomain.com", "mypassword")
    smtp.ehlo()
    smtp.sendmail(fro, to, msg.as_string() )
    smtp.close()
    print("Email send successfully.")

sendMail(
        ["recipient"],
        "hello","cheers",
        []
    )

但是它给我报了以下错误：

raise SMTPSenderRefused(code, resp, from_addr)
smtplib.SMTPSenderRefused: (501, b'5.7.1 <myemail@mydomain.com>... Permission denied', 'myemail@mydomain.com')

有没有人知道怎么解决这个问题？

提前谢谢大家。

这个错误的意思是：在你使用 smtplib.SMTP_SSL 这个实例之前，你需要先调用它的 connect 方法。smtplib.SMTP_SSL 并不会自动连接（smtplib.SMTP 也是如此）。
