Re: Yet another thread about Gnus, isync and dovecot mail stack

[bk@asterio.cloud]

Hi again...
I made some changes and fix paths in both dovecot and mbsync configs and 
successfully login to dovecot, but I receive some errors about 
permissions:
Aug 07 22:14:53 localhost.localdomain dovecot[4724]:

Changes in dovecot.conf:
userdb {
        driver = static
        args = uid=bk gid=bk home=/home/bk/.mail/%d/%n
        default_fields = mail=maildir:/home/bk/.mail/%d/%n
}

in .mbsyncrc:
Path ~/.mail/asterio.cloud/bk/
Inbox ~/.mail/asterio.cloud/bk/Inbox

Permissions of ~/.mail/asterio/bk:
drwxr-xr-x 1 bk bk 62 Aug  7 22:23 /home/bk/.mail/asterio.cloud/bk
