Any update on this? Dovecot 2.3.14 makes doveadm altmove -r functional?

zlib plugin, as far as I know, only supports zstd, gzip, bzip2 and lzma/xz
compression. The last one is being deprecated.

I have found this interesting post in the mailing list:

https://dovecot.org/pipermail/dovecot/2021-February/121329.html


Same problem here with Dovecot 2.3.13, "doveadm altmove -r" is not
moving anything from alternate to default storage. I fixed this by
reverting this commit:

https://github.com/dovecot/core/commit/2795f6183049a8a4cc489869b3e866dc20a8a732


Is this fixed in 2.3.14 ? Does doveadm altmove -r works as expected in 2.3.14?

Regards

Why can't you just pipe the output of "doveadm altmove" command
through an
external command to do the XZ/LZMA compression if dovecot no longer supports
it internally?

And that's set in stone.

So what are the issues with xz? Security? Crashes or viruses on expanding
invalid archives?

Any update on this? Should I fill a bug-report for doveadm altmove -r 
not working?
