Ok, interesting. So... how does dsync do it? Or would it only work between two dovecot servers?
I'm interested in migrating from other servers (Office 365 in one case).
Dsync does not use IMAP protocol to store the mails to storage but instead uses the dovecot storage API to do that. Internally we can set what ever properties we want to including IMAP UIDs and POP3 UIDLs.
Migrating from legacy system should then be done by pulling the mails from the legacy platform by using the imapc connector and storing them by using the internal apis.
We can also store mails to imapc: location but in that case there is many properties that will be lost due to limitations of the IMAP protocol.
Thanks Sami, but I don't see a definitive answer top my question in the above...
So, when migrating from legacy system (legacy = non-dovecot) using imapc, is dovecot able to preserver the UIDs?
Thanks, and my apologies for being a bit dense...
