Exim：根据密件抄送的收件人转发
目前，我通过 .forward 按以下方式过滤传入邮件：
if $header_to: matches "(office|info)@domain.com" then
save Maildir/.office/
endif
if $header_to: matches "[email protected]" then
save Maildir/.whatever/
endif
所以我有一个邮件帐户，它接收不同地址的邮件。基本上我希望它们根据邮件发送到的地址降落在不同的子目录中。
这适用于收件人位于 to 标头中的邮件，但如果收件人位于 bcc 中则不起作用。
当收到使用 bcc 标头发送的邮件时，只有 envelope-to-标头与邮件发送到的真实地址相匹配，并在邮件中提及。 Received-header
Envelope-to: [email protected]
Received: from mail.other.domain ([1.1.1.1])
by mail.domain.com with esmtps (TLS1.0:DHE_RSA_AES_256_CBC_SHA1:32)
(Exim 4.71)
(envelope-from <[email protected]>)
id 1RO5xc-0001TF-Qj
for [email protected]; Wed, 09 Nov 2011 12:04:57 +0100
...
To: [email protected]
我已经尝试过：
if $header_envelope-to: matches ...
但这不起作用，即使使用 To-header 发送邮件，也根本不会过滤邮件（看起来像 Envelope-To-标头不可用在转发文件中）。我应该尝试解析（多个）Received-标头吗？
如何根据真实收件人地址将邮件移至收件人的子目录中？
Currently I am filtering incoming mails by a .forward in the following way:
if $header_to: matches "(office|info)@domain.com" then
save Maildir/.office/
endif
if $header_to: matches "[email protected]" then
save Maildir/.whatever/
endif
So I have a mail account, which receives mails for different addresses. Basically I want them to land in different subdirs based on the address the mail was sent to.
This works for mails where the recipient is in the to-header, but does not work if the recipient was in the bcc.
When a mail is received which was sent with the bcc-header, only the envelope-to-header matches the real address the mail is delivered to and it is mentioned in a Received-header
Envelope-to: [email protected]
Received: from mail.other.domain ([1.1.1.1])
by mail.domain.com with esmtps (TLS1.0:DHE_RSA_AES_256_CBC_SHA1:32)
(Exim 4.71)
(envelope-from <[email protected]>)
id 1RO5xc-0001TF-Qj
for [email protected]; Wed, 09 Nov 2011 12:04:57 +0100
...
To: [email protected]
I already tried:
if $header_envelope-to: matches ...
but this does not work, mails are not filtered at all even when sent with To-header (looks like the Envelope-To-header is not available in forward-files). Should I try to parse the (multiple) Received-headers?
How can I move mails into a subdir of the recipient based on the real recipient address?

看来我终于找到了答案。
这仅检查 local_part，但 afaik 也可以扩展为使用该域，通过
$original_domain（参见 文档）looks like I finally found the answer.
This checks only the local_part, but afaik could be extended to use the domain, too, with
$original_domain(see the doc)变量
$recipients包含所有（to、cc和bcc）收件人。你尝试过吗？The variable
$recipientscontains all (to,ccandbcc) recipients. Have you tried it?
