qmail limiting
Lately there have been some problems with qmail, i guess there are way too many smtp connections being made, and port 25 is being clogged.

there are alot of smtpd processes
its gotten to the point where you can't even connect to port 25 atall
What i did was
i used iptables to block 0/0 (everyone) on port 25
and alllow only my ip.
then i could easily connect to port 25, and send mail to people
Basically what I was wondering was, how could i somehow limit people? or atleast, queue these connections or something.
Because it's all coming at once, and its messing things up
Here's what iplog shows:
