Hey everyone... Thanks in advance for any help. I seem to have the opposite problem that a lot of people have - I've been running Dovecot v. 1.0.10 quite successfully for IMAP for several months. However, one of our executives has her heart set on being able to get her mail via POP3. It looks to me like I have both configured, but when trying to log in via a POP3 or POP3s connection either via a client or through telnet, the connection is created than immediately terminated. Output of dovecot -n: # 1.0.10: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log.dovecot.info log_timestamp: %Y-%M-%d %H:%M:%S protocols: imap imaps pop3 pop3s disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login login_greeting: Dovecot ready login_process_per_connection: no valid_chroot_dirs: /var/spool/mail max_mail_processes: 2048 mail_location: maildir:/home/vmail/%d/%n mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3-login mail_process_size: 1024 mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 imap_client_workarounds: delay-newmail outlook-idle netscape-eoh pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds: outlook-no-nuls oe-ns-eoh oe6-fetch-no-new-mail outlook-idle auth default_with_listener: mechanisms: plain login verbose: yes debug: yes passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: passwd-file args: /etc/dovecot/users socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 Output of telnet: kat at server:~$ telnet localhost pop3 Trying 127.0.0.1...

I have the distinct feeling that I fat fingered something in the conf that I'm just missing. Thanks for the extra set(s) of eyes. Kat
