nslookup is broken in several ways. If dig works, it works :)

You can add 127.0.0.2 to your list, and execute a manual SMTP 
conversation with 127.0.0.2 on your mailserver:

Trying 127.0.0.2...
Connected to 127.0.0.2.
Escape character is '^]'.
220 werkt.niet.net ESMTP NO UCE NO UBE You may be relaytested
ehlo localhost
250-werkt.niet.net Ok.
250-STARTTLS
250-XVERP=Courier
250-XEXDATA
250-XSECURITY=NONE,STARTTLS
250-PIPELINING
250-8BITMIME
250-SIZE
250 DSN
mail from: <>
250 Ok.
rcpt to: <[local address]>
553 5.7.1 Mail from 127.0.0.2 rejected on DNSBL listing

On some systems, you may have to create an alias for 127.0.02 for this 
to work (not needed on linux).
