Obviously will work Douglas Land's answer, with a little addition. 
Suppose you have only localhost.localdomain at $mydestination in main.cf. 
Then add a virtual alias :

<pre><code>something@myhost.com -&gt; somelocaluser@localhost.localdomain
</code></pre>

In main.cf you will need:

<pre><code>alias_maps=hash:/etc/aliases
</code></pre>

Then add to /etc/aliases :

<pre><code>somelocaluser: "|/your/script/here"
</code></pre>

newaliases+postfix reload and you are good to go.

You can pipe an entry to a script via <code>/etc/aliases</code>, RE:

<pre><code>foo: "|/your/script/here"
</code></pre>

modify <code>/etc/aliases</code> then run <code>newaliases</code> and reload the postfix process.

blocks|key|3940654|text|我会检查筛子是否支持管道到脚本。Dovecot支持筛分脚本。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3940655|作为替代，您可以在后缀dovecot之间使用"procmail“作为MDA。Procmail可以传送到脚本。|3940656|(话虽如此，我不知道道格拉斯·兰德的答案为什么行不通，mysql作为后端不应该有什么不同吗？)|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|G|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|H|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|I|8|@]|9|@]|A|$]]]|F|$]]

I would check if sieve supports piping to a script. Dovecot supports sieve scripts.

As alternative you can use "procmail" as MDA between postfix an dovecot. Procmail can pipe to a script. 

(that said I wonder why Douglas Land's answer does not work, mysql as backend should not make a different?!)"

blocks|key|3941081|text|还没有提到的是，您可以使用使用多个查找表+(用逗号或空格分隔)：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3941082|virtual_alias_maps+=+mysql:/etc/postfix/mysql-virtual.cf
alias_maps+=+mysql:/etc/postfix/mysql-aliases.cf+hash:/etc/aliases|code-block|syntax|javascript|3941083|第一个(virtual_alias_maps)将搜索电子邮件并返回用户名(例如:+info@example.com+->+info1234)。|3941084|然后，第二个(alias_maps)将在数据库中搜索用户名，如果找不到，将在/etc/别名中搜索它。这样，您仍然可以在MySQL中管理别名，并在/etc/别名中设置脚本，并且不需要将"@localhost.localdomain“附加到本地用户。|3941085|若要测试设置是否正确，请使用：|3941086|postmap+-q+info@example.com+mysql:/etc/postfix/mysql-virtual.cf

Something that hasn't been mentioned is that you can <a href="http://www.postfix.org/postconf.5.html#alias_maps" rel="nofollow noreferrer">use more than one lookup table</a> (separated by comma or space):

<pre><code>virtual_alias_maps = mysql:/etc/postfix/mysql-virtual.cf
alias_maps = mysql:/etc/postfix/mysql-aliases.cf hash:/etc/aliases
</code></pre>

The first one (virtual_alias_maps), will search for an email and return a username (for example: info@example.com -> info1234). 

Then, the second one (alias_maps) will search for a username in your database, if not found, will search it at /etc/aliases. This way, you can still manage your aliases in MySQL and set your scripts in /etc/aliases, and no need to append "@localhost.localdomain" to the local users.

To test if your setup is correct, use:

<pre><code>postmap -q info@example.com mysql:/etc/postfix/mysql-virtual.cf
postmap -q info1234 mysql:/etc/postfix/mysql-aliases.cf hash:/etc/aliases
</code></pre>

Using Local accounts with aliases in MySQL:

In one of my custom setups, I'm using local accounts for users and MySQL for aliases only. So this is how I set it:

<pre><code>virtual_alias_maps = hash:/etc/postfix/vusers
smtpd_sender_login_maps = hash:/etc/postfix/vusers
virtual_alias_domains = /etc/postfix/vhosts
alias_maps = mysql:/etc/postfix/mysql-aliases.cf hash:/etc/aliases
</code></pre>

As you can see, feel free to mix them anyway you want.

What I'd like to do is set up an address like something@myhost.com which will take whatever email it gets and run the full message as STDIN into a shell script. I can't seem to get this working though. Tried a couple solutions, including this one:

<a href="https://serverfault.com/questions/322657/how-can-i-route-some-emails-to-a-script-in-postfix">How can I route some emails to a script in Postfix?</a>

But my setup is a bit different. I've got the Postfix/Dovecot/MySQL setup, so all email is handled by Dovecot, and Postfix reads its maps from MySQL. Whatever I add to master.cf doesn't seem to work. SpamAssassin has a line in there and that's working fine. I'm stuck!

EDIT:
I really wish people would read carefully before downvoting my question. I am using MySQL for my alias maps, so /etc/aliases does not work, I already tried that of course.

我想做的是设置一个像something@myhost.com这样的地址，它将接收它收到的任何电子邮件，并将整个消息作为STDIN运行到一个shell脚本中。不过，我似乎没办法做到这一点。尝试了几种解决方案，包括这个：如何将一些电子邮件发送到后缀中的脚本？但我的设置有点不同。我已经安装了Postfix/ Dovecot /MySQL，所以所有的电子邮件都由Dovecot处理，Postfix从MySQ
