Bulk export of emails

Continuing the discussion from Export email (.eml):

Is there a way to export ALL emails from a specific timespan to eml-files?
Maybe via API-calls or so?

A customer wants to have these emails in a separate Mailstore and asks for a way of doing that. The mails were fetched from an Exchange server and deleted after fetching … so they don’t have the mails on the Exchange server anymore.

thanks for any pointers, Stefan

Late reply, but you should be able to easily retrieve them by accessing the database.

Never fiddle directly in Zmmads database. Use API calls.
