用python from csv文件发送电子邮件

Question

我在CSV文件中有两封邮件。问题是，它无法登录CSV文件中的第二封邮件。

import smtplib
import email
import csv 

smtp = smtplib.SMTP('smtp.gmail.com',587)
smtp.ehlo()
smtp.starttls()

m = open('msg.txt','r')
message = m.read()



with open('email.csv','r') as f:
   reader = csv.DictReader(f)
   for row in reader:
       smtp.login(row['Addressmail'],row['Password'])
       with open('listmail.csv','r') as h:
            reader1 = csv.DictReader(h)
             for line  in reader1:

                 smtp.sendmail(row['Addressmail'],line['Mail'],message)
