如何使用带后缀的AWS SES接收弹回邮件

Question

我已经配置postfix通过遵循他们的集成指南和发送电子邮件的工作没有问题，以中继邮件到亚马逊SES。

然而，我最近使用一个框架编写了一个PHP应用程序，它生成了一条格式错误的电子邮件。

SES拒绝带有“554 Transaction failed:Expected MIME type，get=”的电子邮件，这是可以接受的。

然而，我的本地postfix服务器随后尝试发送发件人未送达通知，其中包含来自=

SES拒绝声明“提供了501个来自地址的无效邮件（回复来自命令的邮件）”，postfix将从队列中删除跳出消息。

问题是，有什么更简单的方法可以确保我收到最初的554 bounce消息？我看不到让SES中继接受字段为空的方法，所以我相信解决方案在于配置postfix，以便直接将跳转消息传递给我。

请注意，我使用术语“反弹邮件”可能是错误的。邮件可能被拒绝，但我不确定这种情况的正确命名。关键是消息不被SES中继接受，所以它实际上没有“出门”。

Answer 1

你不能说服postfix用以外的任何东西来填写邮件

您可以在main.cf中启用双弹跳通知：

# enable double bounce notifications (resource, software are the defaults)
notify_classes = 2bounce, resource, software

# Set the sender address for 2bounce
# @myhostname will be appended even if you have an @ in the sender
double_bounce_sender = postmaster

# Set the recipient address for 2bounce
2bounce_notice_recipient = [e-mail]
# (and resource, software)
error_notice_recipient = [e-mail]

你最终会得到这样的东西。

PHP app (From: <[e-mail]>) --> SES (To: <[e-mail]>) 
: 5xx Rejected 

Postfix (From: <>) -> SES (<[e-mail]>)
: 501 Rejected Invalid MAIL FROM

Postfix (From: <[e-mail]>) -> SES (<[e-mail]>)

虽然这严格回答了一个问题，即反弹邮件将通过SES进行尝试，但值得注意的是，在电子邮件由于配置问题而失败的情况下，这并不一定比其他答案中建议的将反弹收件人设置为本地邮箱更有用——2反弹邮件将受到相同的配置问题，并且可能也无法发送。

Answer 2

为了接收绑定的邮件，您必须设置一个信封发送者地址，该地址在您的后缀安装中本地传递。

检查

   postconf mydestination

查看哪些域在本地交付。然后，应用程序需要将信封发件人地址设置为有效的本地送达地址。差不多[e-mail]

Answer 3

如果您只需要将Postfix bounce消息发送到收件箱，只需设置下一个与bounce相关的配置参数（/etc/Postfix/main.cf file for Ubuntu）：

# The list of error classes that are reported
notify_classes = bounce, delay, policy, protocol, resource, software

# The recipient of postmaster bounce notifications
bounce_notice_recipient = bounceuser

# The recipient of postmaster notifications about mail delivery problems that
# are caused by policy, resource, software or protocol errors.
error_notice_recipient = bounceuser

# The recipient of postmaster notifications with the message headers of mail
# that cannot be delivered within $delay_warning_time time units
delay_notice_recipient = bounceuser

bounceuser是接收与弹跳相关消息的收件人。如果您需要将邮件转发给非本地收件人，只需编辑/etc/别名，使postfix将邮件转发给您：

# /dev/null will just delete the message from local
bounceuser: /dev/null, <YOUR_EMAIL_ADDRESS_HERE>

不要忘记重新创建别名数据库并重新启动后缀服务：

sudo newaliases
sudo service postfix restart
