In this case regex gives 5 bytes shorter result (without .0/24 at the end). > This also works with IPv6 (one should use > a different bit count for that, though). Did someone receive a spam via IPv6 not from a real MTA?

When I wrote that, I didn't know that sqlite is demonless. I run Exim along with POP3 and web-server on VPS with 64M RAM + 128M swap for $6/month, I don't want to spend more for more RAM, so I wanted minimal memory expense. Please give a link to a sqlite greylisting implementation. -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
