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

<pre>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:
<a href="https://github.com/dovecot/core/commit/2795f6183049a8a4cc489869b3e866dc20a8a732">https://github.com/dovecot/core/commit/2795f6183049a8a4cc489869b3e866dc20a8a732</a></pre>

<div>Is this fixed in 2.3.14 ? Does doveadm altmove -r works as expected in 2.3.14?</div>
<div> </div>

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

And that's set in stone.<br>

So what are the issues with xz? Security? Crashes or viruses on expanding<br>
invalid archives?</div>
