Hi, I am attempting to migrate a mailspool from a cyrus server to a dovecot server using the dsync backup approach as described in the wiki at <https://wiki.dovecot.org/Migration/Dsync>. The first attempt works great. Everything copies over and a quick glance over the spool looks good. Running doveadm backup again though results in the following error: dsync(eggs): Warning: Deleting

...nto the hdr_hash used for comparing mails. Is it possible to get imapc rawlogs to analyze? create a directory that is writeable and add -o imapc_rawlog_dir=/path/to/directory to command line. Also with recent dovecot release you can tell dsync which header fields to hash when matching mails. Add dsync_hashed_headers=Message-ID to config and dovecot will only mach mails using Message-ID header fileld. dsync_hashed_headers setting is supported since dovecot 2.2.33. Sami

...it but it seems to me that dsync should handle this case better. > Currently dovecot does rely on remote to send valid RFC-compliant headers. But you are not alone, we have seen similar problems with mixed header fields on some legacy servers on the migrations we have performed. I have found dsync_hashed_headers setting as a good workaround for migrating mails from broken imap servers. As per RFC Message-ID should be unique and we have safely used setting dsync_hashed_headers=Message-ID to migrate the problematic users away from the broken servers. Sami
