m_dnsbl is a module that is known to not work. It is still on the modules page because the modules page is not currently maintained, but will be updated when the new site is complete.

I see Stealth thank you for your reply. My second solution is your delay join module but there is a problem. The delay join module do the autojoin chans action before the cfg.time but i need a module that will keep waiting the user till the cfg.time so Bopm can check user host and ban hem if he is a proxy. But your module make join action before delay time. I used your 2.0.2 version and if you can change the code for me i will be very happy. The module must wait until delay time and after that time must join the user to the autojoin chans. Can you help me with this issue please.

Modifying the module to do that would require constant checking of each user not on the auto-join channel, which would require timed events and the module would need to loop and check everyone connected to your server every few seconds. This would put unnecessary load on the server.

You'd be better to use a service or bot that monitors connects and uses SAJOIN to move the users to a channel X seconds after they connect. As an added bonus you can have that same bot or service join them to the channel if they are not in any channels for a certain amount of time.
