Hi,
I have been (attempting) to transition a company from in-house dovecot 1.x to a hosted dovecot 2.2 setup.
I am running the doveadm sync command, and for the four mailboxes have been blocked -- sync'ing seem to be copying the same mails, over and over (note, initially I was using doveadm backup but my reading has indicated that 'doveadm sync' is better)
Example:
# date && doveadm -v -o imapc_user=kaye@example.com -o imapc_password=*pass* -o imapc_host=imap.example.com -o imapc_port=993 -o imapc_ssl=imaps -o imap c_ssl_dir=/etc/ssl -o imapc_feature=rfc822.size -o imapc_ssl_verify=no sync -1 -R -u kaye@example.com imapc: Sat Aug 3 09:05:37 UTC 2013 [...] dsync(kaye@example.com): Info: copy from INBOX: box=INBOX, uid=5306, msgid=FB3A2E1C62B148F8B057476BDCBB4A9B@THENORMANS, size=13544 dsync(kaye@example.com): Info: copy from INBOX: box=INBOX, uid=5307, msgid=006b01ce8dad$b8864930$2992db90$@com.au, size=10163563 [...] dsync(kaye@example.com): Info: copy from INBOX: box=INBOX, uid=5311, msgid=< cm.083930.bijjdjk.jdkimlhij.r@createsend5.com>, size=46658 [...]

The exact same number of emails (some in the INBOX, some in the Sent folder) are transferred each time.
In this case, I've firewalled the origin - so their entire mail system is stopped whilst I do the transfer just in case modifications of IMAP flags or additional delivieres might have been the problem.
I am using Dovecot v2.2.4; is this normal expected behaviour? If so, what is the best way to ensure that a migration is done without data loss.
If this isn't expected, has anyone else seen this kind of error before?
Thanks, Anand
