Does the proprietary solution allow IMAP access? If so, I would use imapsync.
Thanks for answers.
Not all the accounts have IMAP enabled, but I guess I could setup some master account with IMAP enabled or even enable IMAP for all users to proceed with migration.
But will imapsync keep trac of UIDs so users won't have have duplicated messages or re-download them if they use POP3? Will it preserve flags of messages so read or deleted messages do not appear as new messages?
regards.

Hello,
I am trying to setup a migration scenario from an proprietary solution to dovecot IMAP/POP3. Whereas am only at the strating point, things appear quite complicated because of the following reasons:
- The proprietary solution uses special/own/proprietary mailbox format (wich is more like maildir but is not maildir)
- I don't have direct access to the filesystem where the mails are stored. The best I could do would be a snapshots of the filesystem
- I have about 1,5TB of mail data.
- Having users to be forced to empty their mailbox before migration or re-download their whole mailbox after migration would be something hard for me to present as a correct option.
Am looking for advices that would avoid me loosing time searching in bad directions. Or even point me to a miraculous tool thatdoes all magic while i have a beer :)
Best regards.
