Postfix configuration

Hello,

might be not the best place to as but i hope the friendly gentoo folks can help me out!

I'm using postix as my MTA and i want to have an email address which i want to use as bounce for my newsletter. It should look like bounce-something@domain.tld
where 'something' is the email address of the reveiver for the newsletter. All the bounce-*@ should go to a scipt for further actions. Thats the easiest way to find the email address in case the mail bounced. I do not want to enable catch rest for the whole domain (spam protection).

I know it has something todo with the canonical feature of postfix but thats all i know. Any wild guesses? It seems i'm unable to find anything specific related to my probem in postfix doc (or i'm just searching in the wrong place)

Thanks guys.

I am having a hard time seeing what exactly you want to achieve - Postfix (or any other MTA) generally does not email messages out again when a DSN like a bounce has to be processed - there are specific configuration options for dealing with these situations.
Perhaps you could explain what it is you are trying to achieve ?

sorry. a little bit unclear.
from the start: I need to catch bounces form my newsletter so i will set this email address "bounce-receiver_email@my_domain.de" as the return path for the newsletter. if it bounces somewhere it will be sent there instead of the original sender which would be apache.

so i need to make sure that all incomming mails to that email address are directed to a script.

i need the email address of the receiver in there because it's the only way to get the original address. actually this is quite common if you check the headers of an email.

Okay, let me try to translate this:
- you have apache mail out a newsletter, that appears to come from newsletter@youdomain.tld ?
- when this is not deliverable, you want it to magically acquire the address BOUNCE_bounced_receiver_address@yourdomain.tld - even though the receiver is probably not in your domain ?

Or what ?
You do realise that you're not at all clear, I hope.

If, as may be the case, you instead just want everything that bounces sent back to a script, that's simple.

And what makes you think that the receiver's address will not be available in a bounced message ?

Since a bounce - or any DSN - only changes the envelope, the original sender and recipient are unchanged.

Just set up a bounce** address and process anything that gets sent there.

I guess.

OT, I hope that your newsletter isn't one of those ... uhm ... SPAM?

The easy way to do this is to create a user account named 'bounced' on your mail server. Then, install procmail and then write a script that processes the bounced mail. Finally, put a pipe to procmail in the .forward file for the user 'bounced':

~bounced/.forward:

Absolutely.

Also, since I presume the "newsletter" mail account will only be used to send mail, you can easily process incoming mail with procmail, since it will be a bounce.
