I have recently gotten Dovecot running on my Solaris 5.8 mail server in order to replace UW IMAP. I'm currently testing it out with mail clients popular amongst my users. It's been working very well, with one vital exception. Apple Mail on OS X 10.4 is not completing authentication (I don't think it's even getting that far). All I'm seeing in the syslog for attempts with Apple Mail (for both IMAP and POP3) is a single line per attempt: Jan 29 17:20:01 paradox dovecot: [ID 107833 mail.info] imap-login: Disconnected: rip=X.X.X.X, lip=Y.Y.Y.Y, TLS handshake This is even with verbose for auth and for SSL. I know syslog plays well with mail.warning and mail.debug and mail.notice, so I'm not quite sure what's going on there. Nothing shows up in authlog or messages either. The OS X 10.5 Apple mail client works just fine, as do Thunderbird and even Eudora. There did not seem to be any coverage of this when I googled and went through the dovecot archives, so I'm thinking it might be some weird interaction between that particular client and the SSL/shadow implementation in dovecot (Things work in UW IMAP for the client). Any suggestions? thanks! # /usr/local/sbin/dovecot -n # 1.0.10: /usr/local/etc/dovecot.conf protocols: imaps pop3s ssl_listen(default): *:997 ssl_listen(imap): *:997 ssl_listen(pop3): *:998 ssl_cert_file: /usr/local/ssl/certs/imapd.pem ssl_key_file: /usr/local/ssl/certs/imapd.pem verbose_ssl: yes shutdown_clients: no login_dir: /usr/local/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/local/libexec/dovecot/pop3-login login_greeting_capability(default): no login_greeting_capability(imap): no login_greeting_capability(pop3): yes first_valid_uid: 100 mail_location: mbox:~/mail:INBOX=/var/mail/%u mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/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/local/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle delay-newmail tb-extra-mailbox-sep imap_client_workarounds(imap): outlook-idle delay-newmail tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xv%08Xu pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: verbose: yes passdb: driver: shadow userdb: driver: passwd Phredd Groves -- Systems Administrator Psychology Department Columbia University [212] 854-8167

Have you looked at the network traffic to see if it even tries to send anything to Dovecot? Maybe it just connects and then sends nothing. -------------- next part -------------- A non-text attachment was scrubbed...

Just wanted to follow this up. I was contacted off list be a few people and confirmed myself that the issue is that the Mac OS X mail client for Tiger (10.4) does not work properly if it is assigned a non-standard port for IMAP or POP3. Once I brought dovecot into production at the standard ports, the Apple mail client for Tiger worked just fine.
