python - 用Python发送邮件主题

Question

当我的程序发送电子邮件时，我无法显示电子邮件的主题部分。我以为我遵循了 SMTP 的 RFC 规范..但我似乎无法弄清楚我做错了什么。非常感谢任何帮助。

def email():

    sender = 'username@domain.com'
    receivers = ['username@domain.com']

    message = """From: From Admin <admin@domain.com>
    To:To Person <user@domain.com>
    Subject: Important Information

    This is a test email message.
    """ 
    try:
        smtpObj = smtplib.SMTP('domain.com', 25)
        smtpObj.sendmail(sender, receivers, message)
        print "Successfully sent email"
    except smtplib.SMTPException:
        print('Error: unable to send email')

不确定您的代码有什么问题。

FWIW，我过去使用 string.join 创建消息正文:

def send_email():
    import string,smtplib

    SMTPserver = "smtp.com"
    # To is a comma-separated list
    To = "sender@domain.com"
    From = "receipient@domain.com"
    Subj = "test subject"
    Text = """test email.
    Not sure what the problem is
    Multi-line anyway."""

    Body = string.join((
        "From: %s" % From,
        "To: %s" % To,
        "Subject: %s" % Subj,
        "",
        Text,
        ), "\r\n")

    s = smtplib.SMTP(SMTPserver)
    s.sendmail(From,[To],Body)

    s.quit()
