AppArmor permissions to create a specific directory

[André Rodier <andre@rodier.me>]

Hello,

I am working on a project to help self hosting emails with Debian.

I reached a point I am satisfied, but I have an issue with AppArmor some
experts may know how to solve.

I have set the rules with Dovecot and AppArmor, and it works very well
so far, except when the mail folder is not existing yet.

Is there any way to write a permission for AppArmor, that will let
dovecot create the maildir folder when it is not exists.

This is the error I have, the first time a user tries to access his mail
box:
> Mar 11 17:45:05 homebox kernel: [  356.357353] audit: type=1400 audit(1520790305.235:176): apparmor="DENIED" operation="mkdir" profile="/usr/lib/dovecot/imap" name="/home/users/andre/mails/" pid=32645 comm="imap" requested_mask="c" denied_mask="c" fsuid=1001 ouid=1001

Obviously, I don't want to add a rule to let dovecot to write in the
home directory!

Thanks for your help,
André
