configuration无法validation – 用户名或密码是否错误？ 从Thunderbird与Ubuntu服务器16.04上的Postfix和Dovecot

所以我在我的Ubuntu Server 16.04上完成了Postfix和Dovecot的一个非常基本的安装，而且我很难用Thunderbird设置/login到我的帐户。

按照本指南中的步骤1-5安装Postfix： https ://www.digitalocean.com/community/tutorials/how-to-install-and-configure-postfix-on-ubuntu-16-04安装Dovecot与帮助从这个链接： https : //help.ubuntu.com/community/Dovecot

我从Thunderbird得到的错误是“configuration无法validation – 用户名或密码是否错误？”。 当我查看系统日志，auth.log和mail.log我无法看到login失败的原因和地方。 Mail.err也不包含任何细节。

如果我运行“postconf -n”，我得到以下内容：

• 为什么后缀默认更改为非chroot进程？
• 致命的：没有SASLauthentication机制
• Postfix：收到不属于我的域名的邮件
• TLS后缀smtp_tls_security_level
• 后缀垃圾邮件阻止不起作用

如果我运行“dovecot -n”，我得到以下内容：

 # 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 4.4.0-93-generic x86_64 Ubuntu 16.04.3 LTS mail_location = maildir:~/Maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = imap service imap-login { inet_listener imaps { port = 993 ssl = yes } } ssl_cert = </etc/ssl/certs/ssl-cert-snakeoil.pem ssl_key = </etc/ssl/private/ssl-cert-snakeoil.key userdb { driver = passwd } 

如果我运行“telnet localhost imap2”，然后A1login用户名密码，我得到这个结果：

 anders@toshiban:~$ telnet localhost imap2 Trying ::1... Connected to localhost. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN] Dovecot ready.

请让我知道，如果有什么我可以添加到这个问题，以帮助您解决这个问题。
