Permissions for dovecot logging

[James Moe]

dovecot 2.3.15
opensuse LEAP 15.4

  I changed logging to use a path rather than syslog. Doing so makes it easier
to work with fail2ban.
  Dovecot fails to start with the error:
Can't open log file /data01/var/log/dovecot.log: Permission denied

  Permissions:
drwxrwxr-x 1 root       users 104 Feb 25  2018 /data01/
drwxrwxr-x 1 sma-user3x users 102 Dec 17 14:50 /data01/var/
drwxrwxr-x 1 sma-user3x users 146 Dec 27 15:37 /data01/var/log/
drwxrwxr-x 1 dovecot    users  22 Dec 27 15:47 /data01/var/log/dovecot/

  "dovecot" is a member of "users".

  What "permission" am I missing?

  Note: A long time ago I had a problem with programs consuming all available
space on the system disk with log or backup files. I have since gotten in the
habit of putting log files on a non-system disk.
