From: Urban Loesch <bind@enas.net> Hi,

...

Well,

so the right syntax (in my case) would be:

-o smtpd_recipient_restrictions = reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_sasl_authenticated,reject,check_policy_service inet:mailstore.example.com:12340

right?? I configured it before the "permit_sasl_authenticated" and the "reject" statement.

...

And eventually, should you suggest me how made some functional verification test?

According to: http://www.postfix.org/SMTPD_POLICY_README.html try on your postfix:

telnet mailstore.example.com 12340

and insert the following lines:

sender=somesender@somedomain.com recipient=your@recipient.com size=12345 [empty line]

Set a size= in bytes which is greater that your configured quota. In theory the policy service should respond with your configured error message "552 5.2.2 Mailbox is full".

Example on my server:

... sender=postmaster@somedomain.com recipient=my@recipient.com size=123450000000

action=552 5.2.2 Mailbox is full ...

For a livetest reduce the quota of your testaccount to ex. 100KB and the send a mail > 100BK from outside to it. You should see the "552" error message in your logs and you should get back a bouncemail from the sending server.

Hope I explained it correct.

Best Urban

WAW! Very very clear your example!

Thanks again Urban, you are a friend ;-)

I will try...

Thanks again to all!

Davide
