I've now upgraded my server to Dovecot v2.2.5 - and the same problem still occurs.

Has anyone else had Dovecot consistently fail to sync remote users?

I've been trying this essentially daily for the last month to finish this migration off, with no success. :-(

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
