EnglishI need to export all the data in order to then migrate it elsewhere. How to export all domains and accounts in Maildir format? Or backup them, if this called as such
I’m aware of this 
Backup - mailcow: dockerized documentation but there’s no mention of Maildir there docs.mailcow.email
The maildir structure is in vmail volume.
However its encrypted. The encryption key is in crypt volume.
Have something to say?

kantamaru267 It’s the ‘vmail’ option:
MAILCOW_BACKUP_LOCATION=/your/backup/path ./helper-scripts/backup_and_restore.sh backup vmail
But, as @esackbauer wrote, the mails are encrypted. See Mail crypt - mailcow: dockerized documentation docs.mailcow.email
how to descrypt all that properly? Simply rinning this script?
# Decrypt /var/vmail
find /var/vmail/ -type f -regextype egrep -regex '.*S=.*W=.*' | while read -r file; do
if [[ $(head -c7 "$file") == "CRYPTED" ]]; then
doveadm fs get compress lz4:1:crypt:private_key_path=/mail_crypt/ecprivkey.pem:public_key_path=/mail_crypt/ecpubkey.pem:posix:prefix=/ \
"$file" > "/tmp/$(basename "$file")"
if [[ -s "/tmp/$(basename "$file")" ]]; then
chmod 600 "/tmp/$(basename "$file")"
chown 5000:5000 "/tmp/$(basename "$file")"
mv "/tmp/$(basename "$file")" "$file"
else
rm "/tmp/$(basename "$file")"
fi
fi
doneYes
DocFraggle but at what point will the description key be used?
kantamaru267 crypt:private_key_path=/mail_crypt/ecprivkey.pem:public_key_path=/mail_crypt/ecpubkey.pem
Here? Or what do you mean?
I see.
Actually, I don’t
1)
private_key_path=/mail_crypt/what’s this path? how can it exist?
2) in the script that’s supposed to descrypt emails:
find /var/vmail/ ....
where it comes from? it doesn’t exist either
# ls /var/vmail
ls: cannot access '/var/vmail': No such file or directoryor should I first a) backup emails b) extract them on my local machie and then c) replace the find /var/vmail/ with the path I’ll have extracted them in?

On my server, the root directory of an instance of mailcow is at /opt/mailcow-dockerized/
