SOLUTION : Wrong storagebasedirectory in table mailboxes . No relation to dovecot.

I want my mailbox data to live on a separate volume , mounted under /mnt/vmail.

Dovecot seems to reference a wrong path when it tries to create directories :

Sep 14 18:16:30 mail dovecot: imap(nk@norbert-klamann.de)<14860><zPutlPjLOo1/AAAB>: Error: mkdir(/mnt/vmail1/vmail1/norbert-klamann.de/n/k/k/nk-2017.10.13.16.59.08//Maildir) failed: Permission denied (euid=2000(vmail) egid=2000(vmail) missing +w perm: /mnt, dir owned by 0:0 mode=0755)

The path should be /mnt/vmail (without the 1 ) / vmail1 etc etc.

I try to find where this path  (/mnt/vmail1/vmail1 ) comes from. My dovecot file is provided via ansible and I have a variable which references  /mnt/vmail for the sieve stuff.

I created the dovecot.conf file with doveconf and amended it with imapsieve.  My dovecot.conf as deployed  is attached
Thanks for any hints !
