Thunderbird (2.0) is all of a sudden checking mail server capabilities and keep posting a popup saying: "Mail Server imap.bard.edu is not an IMAP4 mail server". To the best of my knowledge, neither Tbird nor DC have been updated, though the DC imap host was rebooted today 3 hours ago. Any info on what this is about?
DC is currently serving out of a special port and in evaluation list....I can't imagine that this message would please the user community! Killing and restarting dovecot appears to have at least temporarily stopped this behavior.

Also and perhaps related, I am seeing a syslog message: imap-login: No authentication sockets found child xxxxxx (login) returned error 89

using SSL encrypted IMAP service

Background: DC 1.0, invoked from /etc/rc.local during boot. After stopping and restarting DC, things seem to work again. As per an old problem, I checked /var/run/dovecot, but it was empty with plenty of space. FWIW, the owner/group for login dir (/var/run/dovecot) is dovecot:dovecot, perm 755, while /var/run/dovecot/login is root:dovecot, 750. Host is running AIXV5.3 TL5 SP6 (latest level), DC is compiled with IBM's AIX for C, V6.0 dovecot -n output

# /usr/local/etc/dovecot.conf listen: *:10143 ssl_listen: *:10943 disable_plaintext_auth: no verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 200 mail_location: mbox:~/mail:INBOX=/var/spool/mail/%u:INDEX=/var/dcndx/%u mail_debug: yes mbox_dirty_syncs: no mbox_lazy_writes: no auth default: verbose: yes debug: yes passdb: driver: pam userdb: driver: passwd Do I need to set an O/S or SSL max for authentication sockets? If so, any info would be appreciated

Thanks!
