使用server.connect并将一些东西移到循环之外可以解决此问题

 def Emailspam():
        print("Choose your email provider")
        print("1. Gmail")
        print("2. Outlook")
        provider = input(CRED + ">>> " + CEND)
        os.system("cls")
    
        useremail = input("EMAIL : ")
        userpass = input("PASSWORD : ")
        os.system("cls")
    
        victimemail = input("Victim email : ")
        Content = input('Message : ')
        Number = int(input("Number of mail to send : "))
        os.system("cls")
        
        #https://www.androidauthority.com/gmail-smtp-settings-801100/#:~:text=SMTP%20server%20address%3A%20smtp.gmail,SMTP%20port%20(SSL)%3A%20465
        if provider == ("1"):
            smtp_server = 'smtp.gmail.com'
            port = 587
        #https://support.microsoft.com/en-us/office/pop-imap-and-smtp-settings-for-outlook-com-d088b986-291d-42b8-9564-9c414e2aa040
        elif provider == ("2"):
            smtp_server = 'smtp.office365.com'
            port = 587
        
        else:
            print("Invalid choice")
            skrr = input("press enter to close")
            exit()
    
        try:
            server = smtplib.SMTP(smtp_server,port)
            server.connect(smtp_server,port)
            server.ehlo()
            server.starttls()
            server.login(useremail,userpass)
    
    
            for i in range(0,Number):
                print("Number of Message Sent to " + victimemail + ":" , i+1)
                server.sendmail(useremail,victimemail,Content)
                time.sleep(1)
    
            print("Finished")
            server.close()
    
        except Exception as e:
            print(e)
            print('The username or password you entered is incorrect.')
            p = input("Press enter to close")
            exit()

尝试创建应用程序密码，然后查看它是否有效。要创建应用程序密码，请转到您的帐户并进入隐私设置进行设置。此外，请尝试添加：

server.ehlo()

之后：

server.starttls()

Answer 3

谷歌已经提高了他们的安全性。因此，如果你没有从你的gmail帐户关闭安全性较差的应用程序访问，你将无法登录任何gmail帐户。要做到这一点，请首先单击管理谷歌帐户>；安全选项卡>；不太安全的应用程序访问>；关这是它的一篇文章：How to turn off less secure app access in gmail

另一件事是，您不应该将登录代码保留在for循环中。您应该在for循环之外登录。因此，你将登录一次，并发送电子邮件与该帐户多次

希望能有帮助

以下是工作代码：

def Emailspam():
    print("Choose your email provider")
    print("1. Gmail")
    print("2. Outlook")
    provider = input(CRED + ">>> " + CEND)
    os.system("cls")

    useremail = input("EMAIL : ")
    userpass = input("PASSWORD : ")
    os.system("cls")

    victimemail = input("Victim email : ")
    Content = input('Message : ')
    Number = int(input("Number of mail to send : "))
    os.system("cls")


    if provider == ("1"):
        smtp_server = 'smtp.gmail.com'
        port = 587

    elif provider == ("2"):
        smtp_server = 'smtp.office365.com'
        port = 587

    else:
        print("Invalid choice")
        skrr = input("press enter to close")
        exit()

    try:
        server = smtplib.SMTP(smtp_server,port)
        server.ehlo()
        server.starttls()
        server.login(useremail,userpass)

        for i in range(0,Number):
            print("Number of Message Sent to " + victimemail + ":" , i+1)
            server.sendmail(useremail,victimemail,Content)
            time.sleep(1)

        server.close()

    except Exception as e:
        print('The username or password you entered is incorrect.')
        p = input("Press enter to close")
        exit()
