如何使用python smtplib发送电子邮件到多个收件人?

经过大量的搜索，我无法找到如何使用smtplib。发送邮件到多个收件人。问题是每次发送邮件时，邮件标题似乎包含多个地址，但实际上只有第一个收件人会收到电子邮件。

问题似乎出在邮件上。Message模块期望与smtplb .sendmail()函数不同的内容。

简而言之，要发送给多个收件人，您应该将标题设置为一串以逗号分隔的电子邮件地址。sendmail()参数to_addr应该是一个电子邮件地址列表。

from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
import smtplib

msg = MIMEMultipart()
msg["Subject"] = "Example"
msg["From"] = "me@example.com"
msg["To"] = "malcom@example.com,reynolds@example.com,firefly@example.com"
msg["Cc"] = "serenity@example.com,inara@example.com"
body = MIMEText("example email body")
msg.attach(body)
smtp = smtplib.SMTP("mailhost.example.com", 25)
smtp.sendmail(msg["From"], msg["To"].split(",") + msg["Cc"].split(","), msg.as_string())
smtp.quit()

我尝试了下面的方法，效果很好:)

rec_list =  ['first@example.com', 'second@example.com']
rec =  ', '.join(rec_list)

msg['To'] = rec

send_out = smtplib.SMTP('localhost')
send_out.sendmail(me, rec_list, msg.as_string())

我提出了这个可导入模块函数。本例中使用的邮件服务器为gmail。它分为头和消息，所以你可以清楚地看到发生了什么:

import smtplib

def send_alert(subject=""):

    to = ['email@one.com', 'email2@another_email.com', 'a3rd@email.com']
    gmail_user = 'me@gmail.com'
    gmail_pwd = 'my_pass'
    smtpserver = smtplib.SMTP("smtp.gmail.com", 587)
    smtpserver.ehlo()
    smtpserver.starttls()
    smtpserver.ehlo
    smtpserver.login(gmail_user, gmail_pwd)
    header = 'To:' + ", ".join(to) + '\n' + 'From: ' + gmail_user + '\n' + 'Subject: ' + subject + '\n'
    msg = header + '\n' + subject + '\n\n'
    smtpserver.sendmail(gmail_user, to, msg)
    smtpserver.close()

这对我很管用。

import smtplib
from email.mime.text import MIMEText

s = smtplib.SMTP('smtp.uk.xensource.com')
s.set_debuglevel(1)
msg = MIMEText("""body""")
sender = 'me@example.com'
recipients = 'john.doe@example.com,john.smith@example.co.uk'
msg['Subject'] = "subject line"
msg['From'] = sender
msg['To'] = recipients
s.sendmail(sender, recipients.split(','), msg.as_string())

我使用python 3.6和以下代码为我工作

email_send = 'xxxxx@xxx.xxx,xxxx@xxx.xxx'
server.sendmail(email_user,email_send.split(','),text)

要向多个收件人发送电子邮件，请将收件人添加为电子邮件id列表。

接收者= ['user1@email.com'， 'user2@email.com'， 'user3@email.com']

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage

smtp_server = 'smtp-example.com'
port = 26 
sender = 'user@email.com'
debuglevel = 0

# add receivers as list of email id string
receivers = ['user1@email.com', 'user2@email.com', 'user3@email.com']

message = MIMEMultipart(
    "mixed", None, [MIMEImage(img_data, 'png'), MIMEText(html,'html')])
    message['Subject'] = "Token Data"
    message['From'] = sender
    message['To'] = ", ".join(receivers)
    try:

        server = smtplib.SMTP('smtp-example.com')
        server.set_debuglevel(1)
        server.sendmail(sender, receivers, message.as_string())
        server.quit()
        # print(response)

    except BaseException:
        print('Error: unable to send email')

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

def sender(recipients): 

    body = 'Your email content here'
    msg = MIMEMultipart()

    msg['Subject'] = 'Email Subject'
    msg['From'] = 'your.email@gmail.com'
    msg['To'] = (', ').join(recipients.split(','))

    msg.attach(MIMEText(body,'plain'))

    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.starttls()
    server.login('your.email@gmail.com', 'yourpassword')
    server.send_message(msg)
    server.quit()

if __name__ == '__main__':
    sender('email_1@domain.com,email_2@domain.com')

它只适用于我send_message函数和使用列表中的连接函数与收件人，python 3.6。
