I had to change the gid in the dovecot query

old
user_query = SELECT '/var/vmail/%2d/%d/%n' as home, 
'maildir:/var/vmail/%2d/%d/%n' as mail, 150 AS uid, 118 AS gid, 
concat('dirsize:storage=',quota) AS quota FROM mailbox WHERE username ='%u' 
AND active ='1'
 
new
user_query = SELECT '/var/vmail/%2d/%d/%n' as home, 
'maildir:/var/vmail/%2d/%d/%n' as mail, 150 AS uid, 8 AS gid, 
concat('dirsize:storage=',quota) AS quota FROM mailbox WHERE username ='%u' 
AND active ='1'

It works now, great thanks a lot!
