Hello, I just have a one simple question. my logs has the following entries Sep 9 02:48:10 dovecot: pop3(r): Error: fchown(/home/r/mail/.imap/INBOX/dovecot.index.log.newlock, -1, 12(mail)) failed: Operation not permitted (egid=501(r), group based on /var/mail/r) Sep 9 11:22:30 dovecot: pop3(r): Error: fchown(/home/r/.imap/INBOX/dovecot.index.log.newlock, -1, 12(mail)) failed: Operation not permitted (egid=501(r), group based on /var/mail/r) i know that chmod 0600 /var/mail , will solve the problem and i will no longer receive the above errors again But my question is that incase i did not set chmod /var/mail 0600, can i ignore such errors, is these errors harmful ? if this errors keep coming and i ignored them would this cause mbx corruption .. please advise My dovecot conf is disable_plaintext_auth = no mail_debug yes mail_location = mbox:~/mymail:INBOX=/var/mail/%u mbox_write_locks fcntl passdb { driver = pam } ssl_cert </etc/pki/dovecot/certs/dovecot.pem ssl_key </etc/pki/dovecot/private/dovecot.pem userdb { driver passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } Thanks.
