Hello.
We are running dovecot 2.3.13. Full doveconf -n output below
In 2.3.14 Changelog I found this:
* Remove XZ/LZMA write support. Read support will be removed in future release.
We are using mdbox + XZ/LZMA for alternate storage (messages older than 2 weeks are moved to ALT storage via cron job), so we must convert from XZ to another thing (maybe zstd or bz2).Our cron job script:/usr/bin/doveadm -o mdbox_rotate_interval=14d -o mdbox_purge_preserve_alt=no -o mdbox_rotate_size=250m -o zlib_save=xz -o zlib_save_level=9 altmove -u $userMy first try to accomplish this conversion, without downtime, is this* Pick an user* Move all ALT messages from that user mailbox to MAIN storage location (doveadm altmove -r)* Use doveadm altmove with zstd to recompress messages to ALTI have picked an user, and tried this:/usr/bin/doveadm altmove -r -u myuser allBut it did not work. I expected with that command to move ALL messages from ALT storage to main storage, but 0 messages moved, checked with du -kshWhat is the proper way to recompress messages in ALT storage in mdbox?doveconf -n output:auth_cache_negative_ttl = 10 secs
