it is simply impossible doing on one hand RCPT-verification because
no verification on the root-cause (webserver) but at the same time
not reject messages from the webserver in case verification on the

Is there anyway to populate a cache (file, SQL, ?) with real hard
bounces from remote SMTP and tell postfix to stop send mail to
these addresses next time ?
Postfix logs remote SMTP server responses. You provide a tool
that populates a table with bad addresses, and you

You can push the problem back to the webservers, by using the the
Postfix SMTP server's reject_unverified_recipient feature.
With this, Postfix will make one connection for the recipient
address, and then the Postfix SMTP server answers with 5XX to the

In that case use:
/etc/postfix/main.cf:
smtpd_recipient_restrictions =
...
check_sender_access hash:/etc/postfix/sender_access
...
/etc/postfix/sender_access:
x...@example.com reject_unverified_recipient
example.net
This works like a charm.
One last thing, concerning order of smtpd_recipient_restrictions, I currently
have this in master.cf :
submission inet n - - - - smtpd
...
-o

Can you confirm that in case of greylisting at the destination
SMTP, it will work fine ?
If the remote SMTP server uses greylisting, then the address
verification result will be don't know (*) and the Postfix SMTP server
will reply with 4xx

I made more tests and greylisting is still a problem.
I've tried with :
unverified_recipient_tempfail_action = permit
in main.cf
But I got :
fatal: bad configuration
in mail.log

Hi,
I relay transactional mail for my customer's web sites.
Each website has it's own SASL authenticated account and mail are sent via
submission or smtps.
But, some website doesn't verify email existence when a user submit a web form
or 'create an account'.
That's why I often see my postfix
