尝试使用SMTP发送编码的电子邮件

Question

我尝试过一个程序，允许您发送带编码的电子邮件。 因此，该程序首先要求您的电子邮件地址您要发送邮件的电子邮件密码和电子邮件地址

def get_email(self):
    self.email, ok1 = QInputDialog.getText(self,"Email","Enter your e-mail adress")
    self.passw, ok2 = QInputDialog.getText(self,"Password","Enter your e-mail password")
    self.email_to,ok3 = QInputDialog.getText(self,"Sending To","Enter the email adress that you want to send e-mail")
    if ok1 and ok2 and ok3:
        print(self.email,self.passw,self.email_to)

然后，此处此功能用于向某人发送电子邮件，但必须有错误，因为我无法发送任何电子邮件：

def email_sender(self):
    content = self.encryption()
    mesaj = MIMEMultipart()

    mesaj_govdesi = MIMEText(str(content), "plain")

    mesaj.attach(mesaj_govdesi)

    mesaj["Subject"] = self.subject_text.text()  #LineEdit

    try:
        mail = smtplib.SMTP("smtp.gmail.com", 587)

        mail.ehlo()
        mail.starttls()

        mail.login(self.email, self.passw)  # e-mail adress and it's password
        mail.sendmail(self.email,self.email_to, mesaj.as_string())
        print("Mail Başarıyla Gönderildi....")
        mail.quit()
    except:
        sys.stderr.write("An error occured  ")
        sys.stderr.flush()

如果你想看看这是我用PyQt5和Base64写的整个代码：
