Hi,

running:

dsync -D -v -o mail_fsync=never mirror -R -f -u user@domain imapc:

Where "domain" is a cyrus imap server does not do what the documentation says it does, not even close.

After the first run to an empty mailbox on the dovecot 2.2.13 server all the mails (1.1GB) seem to be correctly synced. I send a test email to the dovecot server and it shows up correctly.

Second run of the above dsync command, first thing that happens is all mails are deleted from the dovecot mailbox (yet the storage used by output of "du -m" doesn't change) and the sync appears to happen again from scratch however the disk space increases again! Now up to about 2GB and another run will take it up a few hundred mb more!

I have tried with multiple different mail storage formats, maildir++, mdbox sdbox, all show the same (except maildir which just complains that INBOX can't be deleted on the second dsync run).

This is frustrating beyond belief, please please anyone who has any insight let me know, the dsync debug output is a little huge to sanitize and post to the list but i can send it individually if anyone has any ideas!

I am ready to give up totally on dovecot but at the same time I just wish it would work!
