我正在运行 Postfix 邮件服务器，为了扫描邮件，我将它们转发给 amavis，扫描完成后，amavis 将邮件转发给密文邮件（自动解密和加密电子邮件的程序）。Ciphermail 将邮件重新发送给 amavis，amavis 将邮件重新发送给 Postfix。
Ciphermail 与 postfix 和 amavis 在不同的服务器上运行。
我想要存档所有解密和加密的邮件，这意味着我想要在传递 ciphermail 之前和传递 ciphermail 之后分别存档一次。为此，我将以下内容插入到/etc/postfix/main.cf
[email protected]
问题是每封邮件存档三次而不是两次。ciphermail 之前存档两次，ciphermail 之后存档一次。我的问题是为什么邮件在 ciphermail 之前发送两次，我如何调整 postfix 以在 ciphermail 之前和 ciphermail 之后分别发送一次邮件。
我已经尝试插入/etc/postfix/main.cf
receive_override_options = no_address_mappings
但是现在邮件只是在 ciphermail 之后存档一次，如果我插入/etc/postfix/master.cf
127.0.0.1:10029 inet n - n - - smtpd
# [...]
-o receive_override_options=no_header_body_checks,no_unknown_recipient_checks,no_address_mappings
在 ciphermail 加密或解密邮件之前，只发送一次邮件副本。
这邮件日志一封邮件发送3份设置：

答案1
免责声明：此答案不包含有关如何使 postfix 密件抄送两次电子邮件的解决方案。我只是解读了您的邮件日志行的内容。
Postfix 部分 pre-content_filter
Feb 3 13:30:25 email1mail postfix/submission/smtpd[3319]: connect from somewhere[xxx.xxx.xxx.xxx]
Feb 3 13:30:25 email1mail postfix/submission/smtpd[3319]: 47F943003E: client=somewhere[xxx.xxx.xxx.xxx], sasl_method=PLAIN, [email protected]
Feb 3 13:30:25 email1mail postfix/cleanup[3323]: 47F943003E: message-id=<[email protected]>
Postfix 接收来自[电子邮件保护]并分配队列 ID 47F943003E
Feb 3 13:30:25 email1mail postfix/qmgr[3313]: 47F943003E: from=<[email protected]>, size=611, nrcpt=2 (queue active)
此时，postfix 已将您的电子邮件设为密件抄送。因此 nrcpt 的值为 2，而不是 1。
Feb 3 13:30:46 email1mail postfix/smtp[3324]: 47F943003E: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=21, delays=0.07/0.01/0/21, dsn=2.6.0, status=sent (250 2.6.0 from MTA(smtp:[192.168.1.102]:10026): 250 2.6.0 Message received)
Feb 3 13:30:46 email1mail postfix/smtp[3324]: 47F943003E: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=21, delays=0.07/0.01/0/21, dsn=2.6.0, status=sent (250 2.6.0 from MTA(smtp:[192.168.1.102]:10026): 250 2.6.0 Message received)
上面两行再次证明 postfix 已经密送了你的邮件并且将其发送到内容过滤端口。
Amavis 部分预芯片邮件
Feb 3 13:30:25 email1mail amavis[3061]: (03061-05) ESMTP:[127.0.0.1]:10024 /var/lib/amavis/tmp/amavis-20150203T130744-03061-ZTBAQ9iE: <[email protected]> -> <[email protected]>,<[email protected]> SIZE=611 Received: from email1mail.localdomain ([127.0.0.1]) by localhost (mail.example.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP; Tue, 3 Feb 2015 13:30:25 +0100 (CET)
这是 amavis 收到两个收件人的电子邮件的证据。
Feb 3 13:30:46 email1mail amavis[3061]: (03061-05) Passed CLEAN {RelayedInbound,RelayedOpenRelay}, BCM [xxx.xxx.xxx.xxx]:59491 [xxx.xxx.xxx.xxx] <[email protected]> -> <[email protected]>,<[email protected]>, Queue-ID: 47F943003E, Message-ID: <[email protected]>, mail_id: XP5xmOE51_t2, Hits: -1, size: 611, queued_as: 250 2.6.0 Message received, 21204 ms
这是 amavis 将电子邮件（有两个收件人）转发给 chipermail 时的日志
Amavis 部分 post-chipermail
奇怪的是当 chipermail 转发回 amavis 时。Chipermail 将原始电子邮件拆分为两封电子邮件，每封电子邮件对应一个收件人。
Feb 3 13:30:47 email1mail amavis[3060]: (03060-06) ESMTP:[192.168.2.10]:10028 /var/lib/amavis/tmp/amavis-20150203T130722-03060-gusE2h0r: <[email protected]> -> <[email protected]> Received: from ciphermail ([192.168.1.102]) by localhost (mail.example.com [192.168.2.10]) (amavisd-new, port 10028) with ESMTP for <[email protected]>; Tue, 3 Feb 2015 13:30:47 +0100 (CET)
Feb 3 13:30:47 email1mail amavis[3061]: (03061-06) ESMTP:[192.168.2.10]:10028 /var/lib/amavis/tmp/amavis-20150203T130744-03061-ZTBAQ9iE: <[email protected]> -> <[email protected]> Received: from ciphermail ([192.168.1.102]) by localhost (mail.example.com [192.168.2.10]) (amavisd-new, port 10028) with ESMTP for <[email protected]>; Tue, 3 Feb 2015 13:30:47 +0100 (CET)
这是电子邮件分裂的证据。两封电子邮件由 amavis 从 chipermail 收到。
Feb 3 13:31:08 email1mail amavis[3061]: (03061-06) Passed UNCHECKED {RelayedTaggedInbound}, ACM [xxx.xxx.xxx.xxx] [xxx.xxx.xxx.xxx] <[email protected]> -> <[email protected]>, Message-ID: <[email protected]>, mail_id: cD-pyG9zKnpK, Hits: -1, size: 1860, queued_as: 96AC730057, 21510 ms
Amavis 将电子邮件（收件人为 carol）转发到 postfix，邮件 ID 为 96AC730057
Feb 3 13:31:09 email1mail amavis[3060]: (03060-06) Passed CLEAN {RelayedOpenRelay}, ACM [xxx.xxx.xxx.xxx] [xxx.xxx.xxx.xxx] <[email protected]> -> <[email protected]>, Message-ID: <[email protected]>, mail_id: l6papfJwmT6R, Hits: -1, size: 871, queued_as: A4AEC3005E, 22636 ms
Amavis 将电子邮件（带有收件人档案）转发到 Postfix，邮件 ID 为 A4AEC3005E
Postfix 部分 post-content_filter
Feb 3 13:31:08 email1mail postfix/smtpd[3340]: connect from localhost[127.0.0.1]
Feb 3 13:31:08 email1mail postfix/smtpd[3340]: 96AC730057: client=localhost[127.0.0.1]
Feb 3 13:31:08 email1mail postfix/cleanup[3323]: 96AC730057: message-id=<[email protected]>
Postfix 收到来自 amavis 的电子邮件，邮件 ID 为 96AC730057
Feb 3 13:31:08 email1mail postfix/qmgr[3313]: 96AC730057: from=<[email protected]>, size=2357, nrcpt=2 (queue active)
Postfix 将您的电子邮件设为密件抄送再次。你可以发现 nrcpt 的值为 2。
Feb 3 13:31:08 email1mail postfix/lmtp[3342]: 96AC730057: to=<[email protected]>, relay=email1mail.localdomain[private/dovecot-lmtp], delay=0.05, delays=0.01/0.02/0.01/0.01, dsn=2.0.0, status=sent (250 2.0.0 <[email protected]> RXUSJ4y/0FQQDQAAXzmN0w Saved)
Feb 3 13:31:08 email1mail postfix/smtp[3343]: 96AC730057: to=<[email protected]>, relay=archiv.example.com[192.168.1.103]:25, delay=0.11, delays=0.01/0.02/0.06/0.02, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 2138426503)
Postfix 不会再次将电子邮件发送到内容过滤器。它将 carol 的电子邮件发送到 dovecot，将 archiv 的电子邮件发送到 archiv 服务器
在另一部分
Feb 3 13:31:09 email1mail postfix/smtpd[3345]: connect from localhost[127.0.0.1]
Feb 3 13:31:09 email1mail postfix/smtpd[3345]: A4AEC3005E: client=localhost[127.0.0.1]
Feb 3 13:31:09 email1mail postfix/cleanup[3323]: A4AEC3005E: message-id=<[email protected]>
Postfix 收到来自 amavis 的电子邮件，邮件 ID 为 A4AEC3005E
Feb 3 13:31:09 email1mail postfix/qmgr[3313]: A4AEC3005E: from=<[email protected]>, size=1358, nrcpt=2 (queue active)
Postfix 将您的电子邮件设为密件抄送再次到自身。您可以发现 nrcpt 的值为 2。
Feb 3 13:31:09 email1mail postfix/smtp[3343]: A4AEC3005E: to=<[email protected]>, relay=archiv.example.com[192.168.1.103]:25, delay=0.08, delays=0.01/0/0.06/0.01, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 26BF726509)
Postfix 将具有两个重复收件人的电子邮件发送到存档服务器
可以看到，postfix 发送了三份邮件后将其传递给 chipermail。您在存档服务器中的登录确认了此行为。
那么，我们如何才能密送电子邮件前传递给 chipermail 吗？
现在，我还没有主意。问题是，postfix 总是将密件抄送的电子邮件传递给 content_filter（chipermail 和 amavis）。这种架构会阻止在将电子邮件传递给 content_filter 之前将其发送到密件抄送地址。
好的，我们怎样才能将唯一的一封电子邮件密送后传递给 chipermail 吗？
您已经有解决方案了，放上receive_override_options = no_address_mappingsmain.cf。
