If they differ, you can can copy those files to another config directory (e.g. conf-d/* -> conf-2.d/), modify the snippets that differ, then include this alternate set of configurations !include conf-2.d/* > Thanks for your suggestion.

dsync panic

As per <http://wiki2.dovecot.org/Migration/Dsync>, I'm running the following command on a local dovecot server to replicate email for a single user from a remote IMAP server: doveadm -D \ -o imapc_host=remote.imap.server \ -o imapc_user=gcr \ -o imapc_password=XXXXXXXX \ -o imapc_list_prefix=IMAP \ -o imapc_features="rfc822.size fetch-headers" \ -o mail_prefetch_count=20 \ -o mail_fsync=never \ backup -R -u gcr imapc: This runs fine for a while and successfully copies quite a lot of mail, but always aborts before completion with the following error: dsync(gcr): Panic: file mail-transaction-log.c: line 271 (mail_transaction_log_rotate): assertion failed: (file->locked) The exit code is 262. Does anyone know why this might happen or how to fix it? -- Greg Rivers

You can run two instances of dovecot, each on a different port or multi-homed listening address. You can share libraries, binaries, log files, but use separate configuration files, specifying different ports/addresses/ssl-configs/auth/access parameters. Then you can fire them both up dovecot -c /dovecot/etc/dovecot-1.conf dovecot -c /dovecot/etc/dovecot-2.conf That's the rough sketch of how to do it. Joseph Tam <jtam.home(a)gmail.com>
