EnglishI have a backup of one of my email accounts in the Maildir format. I made it manually, and it’s not from a Mailcow instance.
How to import it into a Mailcow? Will I also have to create a domain and mailbox for it first?
I’m aware of the 2 import/export bash scripts of Mailcow, however, can they be used in this case?

Have something to say?

I may be wrong with this but I think you can use Thunderbird to do this. I think I did this a while back but don’t remember the exact instructions.
Maybe someone else here can guide you better.
You should create a sync-job in the mailcow-ui, in email -> configuration -> synchronisation.
Sorry, I don’t know the correct wording, I used a german localized version.
@kantamaru267 I think you can just copy the files over to your newly created mailbox directory
The mailboxes are located (in my case) at
/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/
the actual mailbox dir is located at domain/user/Maildir/
Maybe try it first with a test mailbox
DocFraggle let me try
have you done it?
simply copy? or will I have to prepare the domains and mailboxes first by creating them via the UI?
As I learned today that won’t work out of the box as the mails are crypted and compressed. You will need to do that manually
Mail crypt - mailcow: dockerized documentation docs.mailcow.email
DocFraggle have you ever done it?
kantamaru267 yes you have to create the domains and mailboxes before copying the files
I dind’t try this myself as I migrated from an existing mailserver and used the sync jobs to sync the mailboxes.
Basically it should be the same as the restore script does while restoring a vmail backup.
What you have to do after copying the files is to run the “Encrypt /var/vmail” part you can find here: Mail crypt - mailcow: dockerized documentation docs.mailcow.email
This will encrypt and compress your imported mails afterwards
Maybe try it first with a simple test mailbox
If you’re comfortable with the command line, you can look at 
rick sanders imap tools GitHub
There’s a maildir to imap script which could do what you want and the tools are pretty easy to use.
thx, will try
