如何在python ssmtp vs smtplib中发送邮件

pip install secure-smtplib

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

# 设置发件人、收件人和邮件内容
sender = 'your_email@example.com'
receiver = 'receiver_email@example.com'
subject = '邮件主题'
message_body = '邮件正文'

# 创建邮件对象
msg = MIMEMultipart()
msg['From'] = sender
msg['To'] = receiver
msg['Subject'] = subject
msg.attach(MIMEText(message_body, 'plain'))

# 连接到SMTP服务器并发送邮件
try:
    server = smtplib.SMTP('smtp.example.com', 587)
    server.starttls()
    server.login('your_email@example.com', 'your_password')
    server.sendmail(sender, receiver, msg.as_string())
    server.quit()
    print('邮件已成功发送')
except Exception as e:
    print('邮件发送失败:', e)

sudo apt-get install ssmtp

sudo nano /etc/ssmtp/ssmtp.conf

root=your_email@example.com
mailhub=smtp.example.com:587
AuthUser=your_email@example.com
AuthPass=your_password
UseSTARTTLS=YES

import os

receiver = 'receiver_email@example.com'
subject = '邮件主题'
message_body = '邮件正文'

# 创建邮件文件
with open('/tmp/email.txt', 'w') as f:
    f.write(f'Subject: {subject}\n\n{message_body}')

# 使用ssmtp发送邮件
os.system(f'ssmtp {receiver} < /tmp/email.txt')
