使用 Python smtplib 發送郵件時權限被拒絕錯誤

Question

我正在嘗試使用 Python 3.2 發送郵件。 我的代碼如下：

#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",
        []
    )

它給了我以下錯誤：

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

有誰知道如何解決這個問題？

提前致謝。

正如錯誤所說：在嘗試使用它之前，您需要在smtplib.SMTP_SSL實例上調用connect方法。 smtplib.SMTP_SSL不會自動連接（ smtplib.SMTP也不會。）
