当我配置自动回复、sender_bcc 和 always_bcc 时，postfix 会将两封邮件转发给用户。我已经使用 postfix 与 dovecot 和 mysql 进行虚拟用户配置。我不知道问题出在哪里。
当我从发送邮件时[电子邮件保护]到[电子邮件保护]在 main.cf 中我有 always_bcc=pranav@sufalam。以下是日志。

同样，如果我向自动回复用户发送邮件，那么发件人也会收到两封邮件。
答案1
最有可能的是，你有一个内容过滤器，并且在内容过滤器之前和之后都会调用 always_bcc。在内容过滤器之前或之后自定义 smtpd 以包含
-o receive_override_options=no_address_mappings
（请注意，master.cf 中的选项不能包含空格）。
答案2
对我来说 main.cf 中的 ' enable_original_recipient = No' 就起了作用。:-)
