是否可以使用 python 将已发送的电子邮件保存到已发送的项目文件夹中？

Question

我想发送一封电子邮件，但发送的邮件是空的。如何发送电子邮件，然后将其副本放入“已发送”邮件文件夹中。我能做些什么？

Answer 1

是的，有可能。

基本上，您需要创建一封 MIME 电子邮件，然后通过 smptlib 发送它，然后使用 imaplib 将其保存在“发送”上。

imaplib 官方文档。

使用 imaplib 的更详细示例。

这是一个例子：

import time
import ssl
import imaplib
import smtplib
import email

from email import encoders
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

class Mail:
    def __init__(self):
        # considering the same user and pass for smtp an imap
        self.mail_user = 'youruser@yourdomain.com'
        self.mail_pass = 'pass'
        self.mail_host = 'mail.yourdomain'


    def send_email(self, to, subject, body, path, attach):
        message = MIMEMultipart()
        message["From"] = self.mail_user
        message["To"] = to
        message["Subject"] = subject
        message.attach(MIMEText(body, "plain"))

        with open(path + attach, "rb") as attachment:
            part = MIMEBase("application", "octet-stream")
            part.set_payload(attachment.read())
        encoders.encode_base64(part)

        part.add_header(
            "Content-Disposition",
            "attachment; filename= \"" + attach + "\"",
        )
        message.attach(part)
        text = message.as_string()

        context = ssl.create_default_context()
        with smtplib.SMTP_SSL(self.mail_host, 465, context=context) as server:
            result = server.login(self.mail_user, self.mail_pass)
            server.sendmail(self.mail_user, to, text)

        imap = imaplib.IMAP4_SSL(self.mail_host, 993)
        imap.login(self.mail_user, self.mail_pass)
        imap.append('INBOX.Sent', '\\Seen', imaplib.Time2Internaldate(time.time()), text.encode('utf8'))
        imap.logout()


if __name__ == '__main__':
    m = Mail()
    m.send_email('someone@somewhere.com', 'Hello', 'Its just a test!', 'c:\\', 'test.pdf')
