dovecot permission problems

[potuz]

Hello, I recently switched from a fine working postfix MTA with Dovecot to serve IMAP setup to now using Dovecot as an LDA in order to use sieve by adding

Code: Select all

mailbox_command = /usr/libexec/dovecot/dovecot-lda -f "$SENDER" - a "$RECIPIENT"

to main.cf

It works fine for every user except for root's e-mail where I see the following errors in the logfile

Code: Select all

dovecot[7779]: lda(root)<7779>... :Error:chdir(/root/) failed: Permission denied (euid=65534(nobody) egid=65534(nobody) missing +x perm: /root, dir owned by 0:0 mode=0700)
...

And similar. I I make o+x /root I get similar errors inside of /root/.maildir. All my users' maildir directories are mode 0700 and dovecot suid first to the respective user before delivery. How can I fix this?
