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!

Regards

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!

Another thing to check is selinux, is it enabled?  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.
