I'm running sendmail 8.13.8 in linux 2.4.32.

I get connections from spammers that sit in the DATA state for too
long. I figure I want to block them. for example
219.64.113.63.chn.bb-static.vsnl.net.in. So I edit my access.db/txt
file and add:

vsnl.net.in REJECT

I re-makemap or whatever and wait. I still get the connections. This
REJECT does nothing at all. Does anyone know what I have to do to
selectively block specific domains/networks like vsnl.net.in with
sendmail?

Thanks

That notation is deprecated, use :

Connect:vsnl.net.in REJECT

There is one additional problem with the above rule, by using "Connect"
sendmail looks at the reverse name of the IP that does the connection,
and in the case of "vsnl.net.in" it may find "mta3.vsnl.net" or one of
the other 2 servers for that domain. Notice that there is no ".in" in
the name, so there will be no match; you'll need to add more rules to
cover this case, perhaps using IP addresses in other cases with no
reverse.
