Between the MTA and the IMAP4 who should be responsible for archiving? I think if you need to keep copies of e-mails, it's better done at the MTA level. Deliver one copy to the recipient and another copy to the archive. IMHO.

off topic at dovecot but

here is a solution with homebrew postfix/dovecot blog

a good idea is to use maildir for archive / every mail is a file ,you can hash too, depend on how much you have to store you need a storage which should work over years

however you should/prefer use a prof solution

something like

https://www.mailstore.com

cause of legally reasons
