How to reopen a blocked port

Ok guys,

today I've blocked a bunch of ports on our servers with the command

iptables -A INPUT -p tcp --dport 23:24 -j DROP
iptables -A INPUT -p tcp --dport 26:36 -j DROP

etc...

Too bad I've blocked port 26 (exim) and the port of spamd too. How to reopen a blocked port

Any idea how to reopen them?

Thanks in advance How to reopen a blocked port
