Defining a “messagle handler” in Postfix

Question

We are using Postfix for mail delivery and I am trying to make a shell script handle an email sent to foo-bar-baz-bat@example.org.

Is there a way to do this and how?

Answer 1

in /etc/aliases

you should be able to alias to a script like so

foo-bar-baz-bat@example.org: |"/path/to/ScriptOrExecutableHere"

I did this with my Trac installation and it worked like a charm...

EDIT: Oh...i didn't realize you were going to be aliasing dynamic addresses...I think you'd need a script to alias the e-mail addresses as forum threads are created...

EDIT2: Actually you might be able to use the catchall for something like this...

I haven't done it but you would alias "@example.org" to the command. See here for more

Answer 2

Postfix's Before-Queue Content Filter can help:

I wrote a post about how you can use it but you can easily adapt it to your needs:

Answer 3

If the example.org email is only used for discussions you could forward whole @example.org to your script. Or you could use @discussions.example.org.
