[Dovecot] mail_chroot problems / dovecot 1.1rc4
Hello I've noticed a little strange behaviour of that option. For example with following settings: system user: admin, with its home directory as /home/admin dovecot options: as reported by dovecot -n (in attachment) dovecot will try to chroot into /home/home/admin with the following message in logs, in my case: Fatal: chdir(/home/home/admin) failed with uid 1999: No such file or directory The same happens if I use per-user chroot= option in userdb, f.e. in passwd-file I've noticed it's just now, as I've always used explicit chroot dirs specified through passwd-file with /./ (which works perfectly fine, except harmless double slashes in logs), and didn't bother with single system user (I made some chroot/lock related bugreports in distant 1.0rcXX past).
