使用JavaMail API IMAP阅读邮件的回复日期

Question

I am currently reading mail details via IMAP. I am able to collect all the details of Sender, subject and date received. If the mail has been replied, I need to collect the replied date as well. In the mail snapshot attached I am able to see "You replied to this message on" tag with date and time. Is it possible to get the replied date from the current mail using the JavaMail API?

Answer 1

That date is the Date field of a message whose References contain the Message-ID of the message you're currently looking at.

So what you need to do is store your message's message-id, then look for another message in that mailbox that's from the user and mentions that message-id in its References field, and finally you can use that other message's Date.
