ok, I installed zstd successfully, it works - but how i re-compress
everything via dsync ? (on the same server?)<br>
<br>
I did : <br>
<br>
sudo doveadm backup -D -u "${mailbox_username}"
"mdbox:/home/vmail/virtualmailboxes/${mailbox_username}_backup"<br>
sudo service dovecot stop<br>
sudo mv "/home/vmail/virtualmailboxes/${mailbox_username}"
"/home/vmail/virtualmailboxes/${mailbox_username}_original" <br>
sudo mv "/home/vmail/virtualmailboxes/${mailbox_username}_backup"
"/home/vmail/virtualmailboxes/${mailbox_username}" <br>
sudo service dovecot start<br>
<br>
but somehow that does not work correctly, thunderbird claims that
mailboxes are not existing, etc ... <br>
<br>
so what is the correct way to recompress the mailboxes locally ? <br>

<div>Oh, this is with xz, not with gz like we first thought.
There are some known problems with xz, which is why we are
planning on removing it entirely. I'm not sure why v2.3.11
breaks it, although there are some changes related to it but
it might be coincidence. I can't reproduce this problem
though.</div>

</div>
<div>In any case, I'd recommend switching to zlib or to zstd in
v2.3.12. (In theory you could leave the existing mails
xz-compressed, but best would be to re-compress everything via
dsync so old mails can be read when we eventually remove xz
support.)</div>
