Hello!
Could somebody give some feedback on this configuration:
- OpenBSD box with local ssh users.
- /home directory mounted with nosuid,noexec.
- postfix dropping mail in /home/username/mail/INBOX, with the UID/GID of the user.
- dovecot: valid_chroot_dirs = /home default_mail_env = mbox:/home/%u/mail/:INBOX=/home/%u/mail/INBOX
Are there any obvious ways for a local user to help dovecot escape the chroot jail? How can I check that dovecot is REALLY using /home as chroot jail for the imap process?
Thanks!
