Question

我正在尝试使用以下代码向两个用户ID发送电子邮件，任何想法有什么问题？如何发送给多个收件人？

def email1(body,subject):
    print "In email1"
    msg = MIMEText("%s" % body)
    msg['Content-Type'] = "text/html; charset=UTF8"
    msg['Subject'] = subject
    s = SMTP('localhost',25)
    s.sendmail('userid@company.com', ['userid1@company.com','userid2@company.com'],msg=msg.as_string())

Answer 1

将功能组织为更可重复使用的形式：

from smtplib import SMTP
from email.mime.text import MIMEText

def send_email(body, subj, frm, to, host='localhost', port=25):
    msg = MIMEText(body)
    msg['Content-Type'] = 'text/html; charset=UTF8'
    msg['Subject'] = subj
    msg['From'] = frm
    msg['To'] = ', '.join(to) if type(to) == list else to
    smtp = SMTP(host, port)
    smtp.sendmail(frm, to, msg=msg.as_string())

测试它使用内置的SMTP服务器，使用以下命令行在端口3000上运行：

python -msmtpd -n -c DebuggingServer localhost:3000

并发送一些电子邮件：

>>> send_email('Message', 'Spam', 'me@foo.com', ['u1@foo.com', 'u2@foo.com'], port=3000)
>>>
>>> send_email('Message', 'Spam', 'me@foo.com', 'u1@foo.com', port=3000)
>>>

您应该看到：

> python -msmtpd -n -c DebuggingServer localhost:3000
