My table referenced in smtpd_client_restrictions contains

I much appreciated the above suggestion but have not yet got it to work. :(
In main.cf I have ...
smtpd_client_restrictions =
permit_mynetworks
permit_sasl_authenticated
check_client_access pcre:/etc/postfix/client_checks.pcre
reject_unknown_client_hostname
reject_unauth_pipelining
and created the file client_checks.pcre with the content
/Received:\sfrom\s.*bc\.googleusercontent\.com/ REJECT googleusercontent
At various times I have replaced \s with a space and removed the \ from
\. but nothing seems to work. A typical email header line for
googleusercontent is
Received: from dreampairshoes.com
(219.172.193.35.bc.googleusercontent.com [35.193.172.219])
by mail.bristolweb.net (Postfix 3.7.11/8.13.0) with SMTP id unknown

(envelope-from <[email protected]>);
I have been using postfix for several years and thought I'd mastered
this sort of thing but obviously not. :(
