I am doing direct delivery to MX.. and for tajhotels.com I get the above error.. Does this indicate that tajhotels.com domain is black-listed ? and direct delivery won't be possible from our DSL connection ?
Tajhotels is using the spamhaus xbl (a list of compromised / hacked machines) to block mail.
The xbl is a mix of two or three block lists of hacked / compromised IPs that are sending spam.
Your IP is listed in the cbl - http://cbl.abuseat.org/lookup.cgi?ip=61.1.72.10
If that is a static IP, check for things like viruses sending out junk through your mailserver.
If it is a dynamic IP, chances are the guy who had the IP before you was a spammer, or had a virus / open proxy / open relay etc. And you should not be doing direct delivery from dynamic IPs in any case.
