以下是一个使用Python的示例代码，可以将PDF文件保存到本地，并通过电子邮件发送出去。请确保您安装了Python的smtplib和email库。您需要提供自己的发件人和收件人的电子邮件地址，以及发件人的电子邮件密码。

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

def send_email_with_pdf(pdf_file_path, sender_email, sender_password, receiver_email):
    # 创建一个带附件的邮件实例
    msg = MIMEMultipart()
    msg['From'] = sender_email
    msg['To'] = receiver_email
    msg['Subject'] = 'PDF文件'

    # 添加邮件正文
    body = MIMEText('请查收附件中的PDF文件。')
    msg.attach(body)

    # 添加附件
    with open(pdf_file_path, 'rb') as f:
        attach = MIMEApplication(f.read(), _subtype="pdf")
        attach.add_header('Content-Disposition', 'attachment', filename=pdf_file_path)
        msg.attach(attach)

    # 连接到SMTP服务器并发送邮件
    with smtplib.SMTP("smtp.gmail.com", 587) as server:
        server.starttls()
        server.login(sender_email, sender_password)
        server.sendmail(sender_email, receiver_email, msg.as_string())

# 示例用法
pdf_file_path = 'path/to/your/pdf/file.pdf'
sender_email = 'sender@gmail.com'
sender_password = 'password'
receiver_email = 'receiver@gmail.com'
send_email_with_pdf(pdf_file_path, sender_email, sender_password, receiver_email)

请注意，此示例使用了Gmail的SMTP服务器。如果您使用其他电子邮件提供商，请相应地更改SMTP服务器和端口。
