Strange permissions error - Failed to stat sieve storage path

Hi all

I have dovecot-lda set up to run as vmail:vmail, with some sieve scripts in /var/lib/dovecot/sieve.

The sieve scripts fail to be found with the following (detailed and very helpful) error message:

Oct 14 16:13:33 gatekeeper dovecot[8109]: lda(minfrin@example.com)<8109>: Error: sieve: file storage: Failed to stat sieve storage path: stat(/var/lib/dovecot/sieve/vacation.sieve) failed: Permission denied (euid=387(vmail) egid=387(vmail) missing +x perm: /var/lib/dovecot, we're not in group 97(dovecot), dir owned by 97:97 mode=0750)

In this case, the user vmail is a member of the dovecot group:

[root@gatekeeper dovecot]# cat /etc/group | grep vmail mail:x:12:postfix,vmail,opendmarc,opendkim,openarc dovecot:x:97:vmail vmail:x:387: [root@gatekeeper dovecot]# sudo su - vmail Last login: Wed Oct 14 16:15:48 SAST 2020 on pts/0 [vmail@gatekeeper ~]$ wc -c /var/lib/dovecot/sieve/vacation.svbin 530 /var/lib/dovecot/sieve/vacation.svbin

Does dovecot-lda do anything odd with respect to group memberships?
