Thank You Wietse for Your time and patient. I will read RFC first - for now

No, you SPECIFY the null sender address. This concept was introduced
more than 30 years ago. The current definition is in RFC 5321.

With the SMTP protocol:
MAIL FROM:<>

With the Postfix sendmail command:
sendmail -f '' recipients...
sendmail -f '' -t

Hi ,

You suggest to remove sender address. How to do it in Postfix ?

Postfix implements RFC 5321. If an email message has the null envelope
sender address

MAIL FROM:<>

then that email message will not result in a non-delivery notification.

bouce table - where to bounce specified E-mail

[Zalezny Niezalezny]

Hi,

just a short question, is there any possibility in Postfix to control which
E-mail should be bounced and which not ?

We have some relay server which should not bounce some specified test
e-mails (with error). Is there any bounce table ?


Thanks in advance

Zalezny

If you use a "*" wildcard to blindly rewrite everything, that's what
will happen.

You must limit the scope of the rewriting.  The examples in the link
above showed how to do this.

Something like:
@mydomain.local   externalu...@example.com

If you have multiple local fantasy domains, each one needs to be
listed; just add more lines.  No need to list the individual users.
