Do a nslookup on my ISP, ot.com. I guarantee it will FAIL.
Let's see:
dnews/spool-1% nslookup -q=mx ot.com.
Server: DEPT-GW.CS.YALE.EDU
Address: 128.36.0.36
Non-authoritative answer:
ot.com preference = 10, mail exchanger = mail.ot.com
Authoritative answers can be found from:
ot.com nameserver = NS.ot.com
ot.com nameserver = DNS-EAST.PREP.NET
mail.ot.com internet address = 199.234.240.2
NS.ot.com internet address = 199.234.240.5
DNS-EAST.PREP.NET internet address = 129.250.252.10
dnews/spool-0%
No big surprise actually. This lookup is suppoed to be approximately the exact
same one as sendmail does, so If you email address is valid, the lookup should
succeed.
Use the 'host' command instead. I returns error codes prperlly.
Agreed,
