Re: [exim] 4.96-RC1 issue

we are having 100+ rules like these in the central_filter

if $message_body: contains "blah blah"
         logfile /var/log/refuse.log
         logwrite "A1A32 $tod_log $original_domain $message_id
$sender_address"
           fail text "Mail has not been delivered as it is marked as
spam. Check content and resend"
         seen finish
endif

if $message_body: contains "another blah blah check"
         logfile /var/log/refuse.log
         logwrite "A1A33 $tod_log $original_domain $message_id
$sender_address"
           fail text "Mail has not been delivered as it is marked as
spam. Check content and resend"
         seen finish
endif

in the central_filter, removing those delivers the message correctly,
appears that there is an array that is not emptied after each
message_body compare and therefore goobles up memory and fails when
reaching 2gb?
