What software can be used to download addresses (rcpt, from) from mail server messages:?

Question

Mail server

Hi all!
How can I download the addresses of recipients and senders?
There is a mail server on Postfix, Dovecot. But it's hard to do it with them.
There are mail clients left, in ThunderBird I did not find a plugin to parse all letters, and pulled out only addresses from there. Maybe there is something similar in Outlook or Bat:?
Maybe someone knows or faced a similar problem?
Thank you!
