问题描述
为什么我不能用这个脚本发送电子邮件给多个收件人？
Why can't I send emails to multiple recipients with this script?
我没有错误或反弹，第一个收件人 >收到电子邮件。
I get no errors nor bouncebacks, and the first recipient does receive the email. None of the others do.
脚本：
#!/usr/bin/python
import smtplib
SMTP_SERVER = 'smtp.gmail.com'
SMTP_PORT = 587
recipient = '[email protected]; [email protected];'
sender = '[email protected]'
subject = 'the subject'
body = 'the body'
password = "password"
username = "[email protected]"
body = "" + body + ""
headers = ["From: " + sender,
"Subject: " + subject,
"To: " + recipient,
"MIME-Version: 1.0",
"Content-Type: text/html"]
headers = "\r\n".join(headers)
session = smtplib.SMTP(SMTP_SERVER, SMTP_PORT)
session.ehlo()
session.starttls()
session.ehlo
session.login(username, password)
session.sendmail(sender, recipient, headers + "\r\n\r\n" + body)
session.quit()
推荐答案
分号不是收件人标题中地址的正确分隔符。您必须使用逗号。
Semicolons are not the correct separator for addresses in recipient headers. You must use commas.
编辑：我现在看到您正在错误地使用该库。您提供的字符串总是会被解释为单个地址。您必须提供发送给多个收件人的地址列表。
I see now that you are using the library incorrectly. You're supplying a string which will always be interpreted as a single address. You must supply a list of addresses to send to multiple recipients.
