I'm interested in trying out DBMail.

The archive of mail I have is tremendous - with 1000's of messages over
the years, which I would want to import into DBMail. I can't imagine
how long that would take, and I would want to preserve the folder
structure as well as the ability to perform fine-tuned searches based on
headers and content.
I choose postgresql because I'm familiar with it and it's pretty bullet-proof.
I migrated 40,000 without incident.
I think it takes something like .25 seconds per email if you are doing an
imap-to-imap migration.
I did the migration in three iterations.
Iteration one took approximately overnight.
Iteration two took perhaps an hour.
Iteration three (turned off email servers and went offline) took 10-20 minutes.
imapsync is one option. I wrote my own in about an hour.
The real process was to migrate everything in one iteration to a completely
independent imap server on a different machine. I then tested that one for a
week to make sure it would work with my hardware and the database was tuned.
If you use smtp-source (from postfix) you can test delivery scenarios and
volume/rates to your satisfaction.
