problem blocking sender_address

  Good afternoon list.

I apologise for this post.

I am new to postfix and battling to block a sender who keeps changing
digits in the sending address.

I would like to block the sender using the regex
westcoast[0-9]{3}@gmail.com (to block sender address of
westcoast269@gmail.com etc..).

However, adding it to the smtpd_sender_restrictions is not working

config looks like:

smtpd_sender_restrictions =
<snip>
         check_sender_access
regexp:/etc/postfix/sender_access_blacklist_regexp,
</snip>

sender_access_blacklist_regexp contains:

#discard westcoast spammer
westcoast[0-9]{3}@gmail.com DISCARD

Once again

Apologies for the post.

Tom
