This probably is a postfix problem, but I think there are lots of postfix experts/users on this list, and have heard a lot good things about this list, so I am just giving it a try. Thanks in advance!
I am using dovecot-1.0.0-8_56.src.rpm downloaded from atrpms.net, and rebuilt from it(rpmrebuild ...). Postfix is 2.4.3.
I followed documents at http://wiki.dovecot.org/LDA and LDA/Postfix, and used passwd-file (created /etc/passwd.dovecot file) both as password Database and User database. I can send emails, but not receiving, keep getting the "User unknow error". Do I need to change the "local_recipient_map" in main.cf, and if so, how?
Here are some related configuration: ########### dovecot -n ########### # /etc/dovecot.conf log_path: /var/log/dovecot.log ssl_ca_file: /etc/pki/dovecot/certs/ca-bundle.crt verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: Dovecot ready. verbose_proctitle: yes first_valid_uid: 102 mail_extra_groups: mail mail_location: mbox:~/mail:INBOX=/var/mail/%u:INDEX=/var/mail_indexes/%d/%n mail_debug: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail imap_client_workarounds(imap): outlook-idle delay-newmail imap_client_workarounds(pop3): outlook-idle auth default: mechanisms: plain login executable: /usr/local/libexec/dovecot/dovecot-auth verbose: yes debug: yes debug_passwords: yes passdb: driver: passwd-file args: /etc/passwd.dovecot userdb: driver: passwd-file args: /etc/passwd.dovecot socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: mail master: path: /var/run/dovecot/auth-master mode: 384
