hello,
I have some trouble when trying to migrate from another imap server to dovecot with imapc/dsync/doveadm.
when running "doveadm -o imapc_user=foo -o imapc_password=bar backup -R -u localuser imapc:" all is ok.
But when running "doveadm -o imapc_user=foo -o imapc_password=bar sync -R -u localuser imapc:", all local mods are overwritten. For example deleting a message or moving it to trash and it reappear in INBOX (and disappear from trash if moved there). If I try without the reverse flag "-R", local delete reappear two times after two or more sync. If I try without the reverse flag "-R", a message moved to trash is propagated to trash too, but reappear as many times as you "sync" on the two sides in the INBOX. With other users, first "backup -R" is ok but on next sync or backup try, I get :
dsync(other_user): Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted.
Other IMAP server is CriticalPath 8.5.137.
Any clue ??
Emmanuel.

Some news: I tried many things, switching to sdbox, not using "imapc_features = rfc822.size fetch-headers", disabling useless options for a simple test setup etc... with no luck. I switched to isync/mbsync with success in imap to imap mode, syncing all mailboxes/expunge/mailbox creation for each user.
It would be great if dovecot/imapc could be fixed to do it natively. Please tell me if I could help: logs, tests, etc...
Emmanuel.
