It's one of those things I have to poke at on RHEL systems, but I can't remember if it's on by default on Debian Buster. getenforce would answer one way or another. John

Strange behavior but after a reboot of the Dovecot server, the error disappeared from logs (like Windows style! :-)). I'll monitor the situation and take you updated in case it should come back. Thanks all!

Dovecot permission denied errors on NFS after upgrade to 2.2.17
Hi everyone, after some hours when I sent my last e-mail to the ML the problem reoccurred, again problem with some mailboxes reading some e-mails and many errors into dovecot.log like these: /Jul 14 15:07:50 imap(XXX): Error: open(/mnt/mail-storage/XXX/Maildir/cur/1594641298.M607225P10899.XXX,S=4465,W=4534:2,m) failed: Permission denied (euid=501(vmail) egid=501(vmail) missing +r perm: /mnt/mail-storage/XXX/Maildir/cur/1594641298.M607225P10899.XXX,S=4465,W=4534:2,m stat(/mnt/mail-storage/XXX/Maildir/cur/1594641298.M607225P10899.XXX,S=4465,W=4534:2,m) failed: Permission denied)/ SElinux is not installed and Dovecot NFS client uses "defaults" option to mount NFS partition with mailboxes in it and version=3. Don't know where to look further. Any help appreciated!
