Hello everybody,
ive just switched to dovecot imap because dbmail i used before is not developed any further and sql storage is difficult to backup. Ive done that, by setting up dovecot with maildir format and copy mails from old dbmail to new dovecot imap server with my mail client (thunderbird).
Unfortunately migrating to dovecot brought me some problems with my Android K9 Mail client: Sync with IMAP-Server shows me only the oldest mails.
I think the problem is, that K9 only fetches the newest mails (25) from the server (to save memory etc). Which mail is "new" is probably determined by creation timestamp of the email-files in my mailbox, which was copied newest first on migration from dbmail to dovecot. So the older mails have the newer creation timestamp on file system.
Do you have any suggestions how to fix that problem? Maybe migrate to dbox mailbox format?
BTW: New mails show up correctly, as the creation timestamp is new.
Thanks
Lukas
