就像所说的，当我尝试与Thunderbird连接时，Dovecot身份validation失败。 传入和传出的邮件工作正常。
我用例如本教程（以及更多）作为参考： https ： //serverfault.com/questions/ask 。 这应该是好的，因为它是Ubuntu 12.04。 （不幸的是我们不能升级，直到一些遗留的东西被迁移到LXC容器）。
我testing了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-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN
投稿方式：
root@mail ~ # telnet localhost 587 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-PIPELINING 250-SIZE 10240000 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 IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready.
似乎工作…
但是，当我尝试使用Thunderbird（IMAP：153 STARTTLS和SMTP：587 STARTTLS）身份validation连接失败，在mail.log中：

这里是dovecot.conf：

并在Postix master.cf SMTP和提交启用+ SPF添加：
... smtp inet n - - - - smtpd #smtp inet n - - - 1 postscreen #smtpd pass - - - - - smtpd #dnsblog unix - - - - 0 dnsblog #tlsproxy unix - - - - 0 tlsproxy submission inet n - - - - smtpd # -o syslog_name=postfix/submission # -o smtpd_tls_security_level=encrypt # -o smtpd_sasl_auth_enable=yes # -o smtpd_client_restrictions=permit_sasl_authenticated,reject # -o milter_macro_daemon_name=ORIGINATING ... policy-spf unix - nn - - spawn user=nobody argv=/usr/sbin/postfix-policyd-spf-perl
我真的很感激一些gru的帮助，我完全坚持这个：/
最好的祝福，
Temexter
所有提交的参数仍然被注释掉：
submission inet n - - - - smtpd # -o syslog_name=postfix/submission # -o smtpd_tls_security_level=encrypt # -o smtpd_sasl_auth_enable=yes # -o smtpd_client_restrictions=permit_sasl_authenticated,reject # -o milter_macro_daemon_name=ORIGINATING
删除所有#取消注释，您将在所有其他设置中包含smtpd_sasl_auth_enable=yes 。
解决了。 Ubuntu 12.04。 似乎需要不同的参数PAMvalidation。
passdb { driver = pam args = failure_show_msg=yes }
不
args = %s
