Oh, I didn't mention the first error, probably because I thought it was
caused by the latter.
When I run:-
doveadm fs get compress zstd:10:posix:prefix=/
"/mail/zakaria.website/hi@zakaria.website/cur/messagefile"
I get:-
Error: doveadm: Extraneous arguments found:
"/mail/zakaria.website/hi@zakaria.website/cur/messagefile"
And to my dismay, I found out that I missed two needed filesystems named
lists and I included the following at the bottom of the config file, as
note instructed the order matter, refer to, fs_compress, then doveadm
decompressing just worked fine ^^.
fs_compress_read_plain_fallback = yes
fs_compress_write_method = zstd
fs compress1 {
fs_driver = compress
}
fs posix {
}
commad: doveadm fs get "zstd:6:compress:prefix=/"
/mail/zakaria.website/hi@zakaria.website/cur/messagefile
Many thanks for Aki for the heads up 👍

fs_compress is not intended to be loaded like that. It's enough to load
just mail_compress.

In maildir format, you will find cur folder, it should contain all
emails in inbox and you can open it unless it was compressed and if it
was you can use doveadm to decompress it:-
e.g. :- doveadm fs get compress zstd:6:posix:prefix=/
"/mail/zakaria.website/hi@zakaria.website/cur/MESSAGEFILENAME"
I tested this on dovecot 2.3 and it works. To Timo and Aki, this
failed
on dovecot 2.4, it throws the following errors, it could be a bug in
this release:-
Debug: conn unix:/var/run/dovecot//stats-writer: Connecting

/usr/lib/dovecot/libfs_compress.so:
Module doesn't have init function
These are my relevant configuration, I placed them at top and bottom
of
the configuration file and it didnt make any difference:-
mail_plugins = mail_compress fs_compress
fs_compress_write_method = zstd
mail_compress_write_method = zstd
compress_zstd_level = 10
fs_compress_read_plain_fallback = yes
With thanks.
