电子邮件地址标记不适用于 postfix 中的虚拟邮箱

  • 772

我有自己的电子邮件服务器，我希望能够使用动态电子邮件地址标记。我将recipient_delimiter = +-指令添加到我的配置并重新启动后缀，但现在如果我发送电子邮件[email protected]，电子邮件将被退回，并显示错误“未知用户”。如果我发送电子邮件[email protected]，电子邮件将按预期发送到webmaster帐户。

这是我的后缀配置：

## These are all default Postfix settings that we won't change
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
append_dot_mydomain = no
biff = no
broken_sasl_auth_clients = yes
inet_interfaces = all
mailbox_command = /usr/lib/dovecot/deliver -c
    /etc/dovecot/conf.d/01-mail-stack-delivery.conf -m "${EXTENSION}"
mailbox_size_limit = 0
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +-
relayhost =
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_sasl_auth_enable = yes
smtpd_sasl_authenticated_header = yes
smtpd_sasl_path = private/dovecot-auth

smtpd_sasl_type = dovecot
smtpd_tls_auth_only = yes
smtpd_tls_received_header = yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
tls_random_source = dev:/dev/urandom

从/etc/postfix/master.cf，我有这个定义的 Dovecot：

dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver
  -f ${sender} -d ${recipient}

我也有 , , , , , , 和一堆其他的定义ifmail，bsmtp但scalemail-backend我mailman不uucp完全scache确定maildrop它们都做了什么。

有谁知道这里发生了什么以及我该如何解决它？

我正在使用虚拟邮箱。

    在/etc/postfix/master.cf配置文件中，确保配置参数dovecot引用的服务定义virtual_transport设置为在调用/usr/lib/dovecot/deliver.

    例如，这可能不起作用，因为${recipient}它将被[email protected]Postfix 的pipe(8)服务扩展为：

    dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=dovecot:dovecot argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient}

    在这种情况下，${recipient}宏应该被替换为${user}@${domain}，以便 Dovecot 交付代理[email protected]在其命令行中接收正确的地址：

    dovecot   unix  -       n       n       -       -       pipe
  flags=DRhu user=dovecot:dovecot argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${domain}

  2. 参数中的多个字符recipient_delimiter似乎仅在 Postfix 2.11 或更高版本中受支持。确保您正在运行最新的 Postfix 版本，或者仅使用一个分隔符。

    从postconf (5)手册页：

    收件人分隔符（默认：空）

    可以将用户名与其扩展名（例如：user+foo）或 .forward 文件名与其扩展名（例如：.forward+foo）分开的字符集。基本上，软件会先尝试 user+foo 和 .forward+foo，然后再尝试 user 和 .forward。此实现识别每个电子邮件地址或 .forward 文件名的一个分隔符和一个扩展名。

    当 recipient_delimiter 集包含多个字符（Postfix 2.11 及更高版本）时，用户名或 .forward 文件名与其扩展名由匹配 recipient_delimiter 集的第一个字符分隔。
