Yeah it makes sense. 2.4 looks much more organised and structured with
named lists whether set in options tags or processed under the hood
utilising the dovecot.conf. I think such implementation enforces
additional security to the mail file system through restricting and
limiting the mean to access the filesystem. Please correct me if
anything I might've misunderstood.
I tested your command and it works perfectly.

That's because the doveadm fs syntax has changed.
Try
doveadm -o fs=compress,posix -o fs/compress/fs_driver=compress -o
fs/posix/fs_driver=posix -o
fs_posix_prefix=/mail/zakaria.website/hi@zakaria.website/ fs get test
cur/messagefile

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 👍
