dovecot - Jul 2015 - Importing mbox archives into a inbox?

Greetings from a dovecot newbie. I have a bunch of mailing list archives 
(in mbox) format that I want to dump into the inbox for a particular 
account on the system. I want them to retain all of their information, 
particularly the date. I'm not seeing how to do this, but I could be 
missing it. Is this LDA or LMTP with some command-line options I'm not 
seeing?

If you use Maildir at the destination I suggest
