ubuntu 上的邮件服务器(postfix+dovecot+squirrelmail)

我必须设置一个邮件服务器（ubuntu 云服务器），我正在我的家用电脑（ubuntu vm）上准备它，以确保我的经理可以正常工作。我首先从 Postfix、Dovecot 和 Squirrelmail 开始，遵循教程如果在这里可以正常工作，那么我就可以开始在云服务器上执行此操作。家用计算机具有动态公共 IP 地址（仅当我重新启动路由器时，IP 才会更改），并且我已为该公共 IP（A- lts.mooo.com，MX- maillts.mooo.com）注册了一个试用域，该域可以全局解析。

我在向服务器发送和接收邮件时遇到了问题。我无法向 Gmail 帐户发送邮件，但我可以向 Yahoo 发送邮件 2、3 次，之后就不能了（日志显示如下）。

以下是我的邮件服务器配置，

后缀：

myhostname = lts.mooo.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = mooo.com, lucid, localhost.localdomain, localhost
relayhost =
mynetworks = 192.168.1.4 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all

smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth-client
smtpd_sasl_local_domain = mooo.com
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_sasl_auth_enable = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
#inet_interfaces = all



smtpd_tls_auth_only = no
smtp_tls_security_level = may
smtpd_tls_security_level = may
smtpd_tls_CAfile = /etc/ssl/certs/cacert.pem
smtp_tls_note_starttls_offer = yes
smtpd_tls_loglevel = 1
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom



home_mailbox = Maildir/
smtpd_sasl_authenticated_header = no
smtpd_sender_restrictions =
mailbox_command =
smtp_use_tls = no
smtpd_tls_mandatory_protocols = SSLv3, TLSv1
smtpd_tls_mandatory_ciphers = medium

鸽舍：只需根据教程进行更改即可。

/var/log/mail.log：

我没有收到任何从外部域发送的邮件（雅虎、谷歌到[电子邮件保护]) 但是（我知道没有选择动态公共 IP，但想检查它是否有效）。我需要一些帮助，以便我可以从任何域接收邮件并发送到任何域。

我希望有些人正在运行他们自己的邮件服务器，并且可以帮助我找出我做错的地方，并提供一些线索和信息以达到我的目标。

谢谢你！

mooo.com 的 MX 记录显示您的邮件由 mail.afraid.org 处理。当我尝试发送电子邮件至[电子邮件保护]通过 mail.afraid.org，它显示“虚拟地址表中的用户未知”。

至于为什么您的外发邮件失败，请查看您的日志：

Connections will not be accepted from 183.82.61.111, because the ip is in Spamhaus's list

您似乎搞不清楚您是为 mooo.com 还是 lts.mooo.com 发送和接收邮件。如果您希望 maillts.mooo.com 接收发送至[电子邮件保护]，则您需要为 mooo.com 指定一个 MX 记录，该记录指定 maillts.mooo.com，而不是 mail.afraid.org。按照现在的设置，它应该会收到以下电子邮件：[电子邮件保护]，但是您的 Postfix 配置似乎没有在 mydestination 部分中指定这一点。
