Не работает авторизация Dovecot SASL

Как уже было сказано, аутентификация Dovecot не работает, когда я пытаюсь подключиться к Thunderbird. Входящая и исходящая почта работает нормально.

Я использовал, например, этот учебник (и многие другие) в качестве справочника: https://serverfault.com/questions/ask . Это должно быть нормально, поскольку это для Ubuntu 12.04. (который, к сожалению, мы не можем обновить, пока некоторые устаревшие вещи не будут перенесены в контейнер LXC).

Я тестировал auth:

root@mail ~ # doveadm auth prta
Password:
passdb: prta auth succeeded
extra fields:
user=prta

SMTP:

root@mail ~ # telnet localhost 25
Trying 127.0.0.1...
Connected to mail.prteamwork.com.
Escape character is '^]'.
220 mail.prteamwork.com ESMTP Postfix
ehlo localhost
250-mail.prteamwork.com

250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

Отправка:

root@mail ~ # telnet localhost 587
Trying 127.0.0.1...
Connected to mail.prteamwork.com.
Escape character is '^]'.
220 mail.prteamwork.com ESMTP Postfix

250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

IMAP:

root@mail ~ # telnet localhost 143
Trying 127.0.0.1...
Connected to mail.prteamwork.com.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE

Кажется, работает ...

Но когда я пытаюсь подключиться к Thunderbird (IMAP: 153 STARTTLS и SMTP: 587 STARTTLS), аутентификация не выполняется, в mail.log:

Вот dovecot.conf:

disable_plaintext_auth = no
mail_privileged_group = mail
mail_location = mbox:~/mail:INBOX=/var/mail/%u
userdb {
driver = passwd
}

passdb {
args = %s
driver = pam
}
protocols = " imap"

protocol imap {
mail_plugins = " autocreate"
}
plugin {
autocreate = Trash
autocreate2 = Sent
autosubscribe = Trash
autosubscribe2 = Sent
}

service auth {
unix_listener /var/spool/postfix/private/auth {
#group = postfix
mode = 0660
#user = postfix
}
}

auth_mechanisms = plain login

ssl=required
ssl_cert = </etc/ssl/certs/mail.prteamwork.pem
ssl_key = </etc/ssl/private/mail.prteamwork.key

Вот ' s Postix main.cfg:

#Base config
myhostname = mail.prteamwork.com
myorigin = /etc/mailname
mydestination = $myhostname, $mydomain, localhost, localhost.$mydomain
relayhost = 
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128

#DKIM
milter_default_action = accept
milter_protocol = 6
smtpd_milters = inet:localhost:8891
non_smtpd_milters = inet:localhost:8891

И в Postix master.cf включены SMTP и отправка + добавлен SPF:

...
smtp      inet  n       -       -       -       -       smtpd

Я был бы очень признателен за помощь gru, я полностью застрял в этом: /
