Hello, I'm trying to get dovecot and postfix virtual domains working on an fc6 system. My software versions are postfix 2.4.5 installed from rpm and dovecot 1.0.3 also installed from rpm. I'm only running secure protocols, pop3s at the moment, imaps later on. I've set up postfix for virtual mailbox domains as per it's howto on the subject and confirmed that email sent gets delivered to the virtual area, which in this case is /home/vmail/domain.com/username, there's a maildir under that. In this case the user is a shell user who has a login, in all other cases the users will be completely virtual, having no login account and being completely virtual. When i atempt to get mail from the server using this user, the one with the login, i am getting a can not map username coming from dovecot. Here's my config: # 1.0.3: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info protocols: pop3s ssl_ca_file: /etc/dovecot/ca-cert.pem ssl_cert_file: /etc/dovecot/pop.cert ssl_key_file: /etc/dovecot/pop.key ssl_cipher_list: ALL:!LOW disable_plaintext_auth: yes login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/pop3-login valid_chroot_dirs: /var/spool/vmail mail_extra_groups: mail mail_location: maildir:/home/vmail/%d/%u maildir_copy_with_hardlinks: yes mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib64/dovecot/pop3 auth default: mechanisms: plain login verbose: yes passdb: driver: passwd userdb: driver: passwd I'd appreciate any pointers. I think i am close, but am not seeing it. Thanks. Dave.
