无法验证配置 - 用户名或密码是否错误？来自 U​​buntu Server 16.04 上带有 Postfix 和 Dovecot 的 Thunderbird

因此，我在 Ubuntu Server 16.04 上完成了 Postfix 和 Dovecot 的基本安装，但在使用 Thunderbird 设置/登录我的帐户时遇到了麻烦。

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 通过以下链接安装 Dovecot：https://help.ubuntu.com/community/Dovecot

我从 Thunderbird 收到的错误是“无法验证配置 - 用户名或密码是否错误？”。当我查看 syslog、auth.log 和 mail.log 时，我无法看到登录失败的原因和位置。Mail.err 也不包含任何详细信息。

如果我运行“postconf -n”，我会得到以下结果：

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
home_mailbox = Maildir/
inet_interfaces = all
inet_protocols = all
mailbox_size_limit = 104857600
mydestination = $myhostname, example.com, mail.example.com, localhost.example.com, localhost
myhostname = localhost.localdomain
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost =
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_use_tls = yes
virtual_alias_maps = hash:/etc/postfix/virtual

如果我运行“dovecot -n”，我会得到以下结果：

# 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”，然后运行 ​​A1 LOGIN 用户名密码，我会得到以下结果：

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.

请让我知道我是否可以对这个问题添加任何内容，以帮助您帮我解决这个问题。

致以最诚挚的问候 Anders

使用 imap.example.com 和 smtp.example.com 的正确设置更新了我的 DNS，并使其正常工作。
