使用python脚本从CPanel电子邮件发送电子邮件

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

sender_email = "your_email@example.com"
receiver_email = "recipient_email@example.com"

subject = "邮件主题"
body = "邮件正文"

message = MIMEMultipart()
message["From"] = sender_email
message["To"] = receiver_email
message["Subject"] = subject

message.attach(MIMEText(body, "plain"))

attachment = open("path_to_attachment_file", "rb")

part = MIMEBase("application", "octet-stream")
part.set_payload((attachment).read())
attachment.close()

part.add_header("Content-Disposition", "attachment; filename=attachment_file_name")
message.attach(part)

smtp_server = "smtp.example.com"
smtp_port = 587
smtp_username = "your_smtp_username"
smtp_password = "your_smtp_password"

with smtplib.SMTP(smtp_server, smtp_port) as server:
    server.starttls()
    server.login(smtp_username, smtp_password)
    server.sendmail(sender_email, receiver_email, message.as_string())
