python办公自动化------邮件发送

拿163邮箱举例

一、开启邮箱的POP3/SMTP服务并拿到授权密码

要开启POP3/SMTP服务

复制授权密码，一会要使用

 

二、发送邮件

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

# 我的邮箱配置
mail_host = "smtp.163.com"
mail_user = "[e-mail]"
mail_pass = "KThe***********"

sender = "[e-mail]"
# 收件人的邮箱
receivers = ["[e-mail]"]

# 邮件的内容
message = MIMEText("你好", "plain", "utf-8")
message["Subject"] = "2025年第一季度报告"
# 想要收件人看到的邮箱名称
message["Form"] = "神秘人"
# 要发送给的人
message["To"] = receivers[0]

# 正式发送邮件
try:
    smtpObj1 = smtplib.SMTP_SSL(mail_host, 465)
    # smtpObj1.set_debuglevel(1)
    smtpObj1.login(mail_user, mail_pass)
    smtpObj1.sendmail(sender, receivers, message.as_string())
    smtpObj1.quit()
    print("邮件发送成功")
except Exception as e:
    print("error", e)

 三、发送包含附件的邮件

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

# 我的邮箱配置
mail_host = "smtp.163.com"
mail_user = "[e-mail]"
mail_pass = "KTh************"

sender = "[e-mail]"
# 收件人的邮箱
receivers = ["[e-mail]"]

# 邮件的内容
# message = MIMEText("你好", "plain", "utf-8")
# MIMEMultipart()可以用来传输附件，也可以用来传输文本
message = MIMEMultipart()
message["Subject"] = "2025年第一季度报告"
# 想要收件人看到的邮箱名称
message["Form"] = "神秘人"''
# 要发送给的人
message["To"] = receivers[0]
content = MIMEText('附件请接收', 'plain', 'utf-8')
message.attach(content)

with open('./dataFile/测试文件转换.pdf', 'rb') as f:
    att = MIMEText(f.read(), 'base64', 'utf-8')
    att['Content-Type'] = 'application/octet-stream'
    att["Content-Disposition"] = 'attachment; filename=test.pdf'
    message.attach(att)

# 正式发送邮件
try:
    smtpObj1 = smtplib.SMTP_SSL(mail_host, 465)
    # smtpObj1.set_debuglevel(1)
    smtpObj1.login(mail_user, mail_pass)
    smtpObj1.sendmail(sender, receivers, message.as_string())
    smtpObj1.quit()
    print("邮件发送成功")
except Exception as e:
    print("error", e)

运行结果：
