Delay makes your simultaneous connections number grow because time you spend for serving a connection becomes greater with delays. Defer would work better here - it does not require to hold a connection but reduces spammer's sending speed. Just add hosts you want to delay connection with to your greylist and do not let them send more than 1 message per 2 or 5 minutes. -- Cronfy. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
