Just wanted to know if we have any other ways to block conncet= ions?

Quo= th Stanley Lieber <sl@stanleylieber.com>:
check out iwhois (documented in the tel man page).

also: lookman dns.

the existing tools are fairly manual and rudimentary.

there=E2=80=99s no generic firewall, b= ut upas has some filtering options. smtpd(8) reads the file /mail/blocked for blocke= d addresses, and has the -k flag to block ip addresses manually. the v= alidatesender script (called by upas) checks for a spamhaus file at /mail/li= b/spamhaus. there are also ratfs(4) and scanmail(8), which provide more comp= lex filtering mechanisms.
