I'm trying to get Dovecot working on Rocky 9.5.
In 10-mail.conf I have: mail_privileged_group = mail mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u
In /var/spool: drwxr-x---. 3 mail mail 64 Dec 13 16:29 mail
In /var/spool/mail: -rw-rw----. 1 peter mail 500 Dec 13 16:29 peter
When I try to login using Telnet I get the following in /var/log/maillog: Dec 13 17:03:23 Backup dovecot[690594]: pop3-login: Login: user=<peter>, method=PLAIN, rip=172.21.10.5, lip=172.21.10.5, mpid=690664, secured, session=<8Or5zikp7uCsFQoF> Dec 13 17:03:23 Backup dovecot[690594]: pop3(peter)<690664><>: Error: Couldn't open INBOX: Permission denied Dec 13 17:03:23 Backup dovecot[690594]: pop3(peter)<690664><>: Disconnected: Couldn't open INBOX: Permission denied top=0/0, retr=0/0, del=0/0, size=0
(There is a random data between <> - I've deleted it as I'm not sure if it is sensitive.
I'm certain I'm typing the password correctly in Telnet and I think the first of the three lines from the log indicate that I successfully connected. But why do I get Permission denied when Dovecot tries to open the INBOX? As far as I can see I've set them right (as per the permissions pasted above).
