尝试发送电子邮件时执行 excel 列表中的行时出错

Question

我正在构建一个邮件发件人，我想一次接收一封电子邮件，而不是将所有收件人都添加到密件抄送中。

因此，使用下面的代码，我试图让它从 .xlsx 列表中一次添加一封电子邮件，将其添加到“收件人”并发送电子邮件，然后在下一行重复.xlsx 文件。

我的代码如下所示：

import pandas as pd

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

email_list = pd.read_excel('/home/xxxx/test.xlsx')

emails = email_list['EMAIL']
email_list['EMAIL'] = email_list.index

my_list = email_list['EMAIL'].tolist()
print(my_list)


msg = MIMEMultipart()
msg['From'] = "test@xxxx.com"
msg['To'] = ",".join(str(my_list))
msg['Subject'] = "This is the subject"

message = """
<html><p>randomtext</p></html>
"""
message2 = "plain text msg"
msg.attach(MIMEText(message,'html'))
msg.attach(MIMEText(message2,'plain'))
Password = "thisispassword"
server = smtplib.SMTP('smtp.mail.com:587')
#server.ehlo()
server.starttls()
server.login(msg['From'],Password)
server.sendmail(msg['From'],msg['To'],msg.as_string())

server.quit()

相反，我收到以下错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/seniori/anaconda3/lib/python3.8/smtplib.py", line 885, in sendmail
    raise SMTPRecipientsRefused(senderrs)
smtplib.SMTPRecipientsRefused: {'[,0,,, ,1,,, ,2,]': (501, b'<[,0,,, ,1,,,=,2,]>: missing or malformed local part')}

它似乎在 excel 文件中找到行，但找不到电子邮件地址。

知道我需要在此处更改什么吗？

电子邮件列表是 UTF-8 excel.xlsx 文件，如下所示：

EMAIL
test@gmail.com
test1@gmail.com
test2@gmail.com

Answer 1

我已经通过执行以下操作解决了这个问题：

for i in range(0,len(emails)):
    msg['To'] = my_list[i]
    server.sendmail(msg['From'],msg['To'],msg.as_string())
    del msg['To']

这是一个循环，一次从 excel-sheet 发送一封电子邮件。

Answer 2

STMP.sendmail 期望 to_addrs 参数是一个 list:

... list of RFC 822 to-address strings (a bare string will be treated as a list with 1 address)

邮件body中的TOheader可以（必须）是comma-separated字符串，但sendmail的参数必须是列表

所以你的代码应该是

server.sendmail(msg['From'], mylist, msg.as_string())
