Duas semanas atrás eu configurei um Mailserver usando Dovecot e Postfix. É um servidor para uma organização com cerca de 5000 e-mails por dia. Tudo funciona bem, mas hoje eu habilitei verbose_ssl
em /etc/dovecot/conf.d/10-logging.conf
e recebi essas mensagens de erro para quase todos os Login IMAP:

Encontrei apenas uma pergunta no stackoverflow com entradas de log semelhantes, mas a resposta é incluir todos os certificados intermediários, que eu já fiz.
Meu /etc/dovecot/conf.d/10-ssl.conf
(comentários removidos):
ssl = required
ssl_cert = </etc/ssl/certs/my-domain.de
ssl_key = </etc/ssl/private/my-domain.de
ssl_dh_parameters_length = 2048
ssl_protocols = !SSLv2 !SSLv3
ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL
ssl_prefer_server_ciphers = yes
Alguém sabe, o que essas entradas unknown state
em mail.log realmente significam?
