Dear All,
My Friend is facing a problem he is not able to send mails from outside for e.g yahoo.com his mx is natted on the firewall to my exchange server.
Sender gets a bounce back mail stating below: -
<XXX>:
203.X.X.X does not like recipient.
Remote host said: 550 5.2.1 Mail from 209.X.X.X refused: spam site.
Giving up on 203.X.X.X.
Sorry but i dont know whether this forum should answer my querries which are actually of my friends.
But if you could it would be really helpful.
Thanks in advance.

Hi Ranjit,
203.X.X.X does not like recipient.
Remote host said: 550 5.2.1 Mail from 209.X.X.X refused: spam site.
Giving up on 203.X.X.X.
implies that the recipient server is using antispam or blacklist software to refuse connections from certain IP addresses, including the 209.x.x.x address you cited.
I would consider using an RBL lookup tool such as
http://www.mxtoolbox.com/blacklists.aspx to check the 209.x.x.x address against different RBLs.
If it turns out that it is indeed listed, you would need to go to the respective listing site to see how to get off their list.
( I am not affiliated with mxtoolbox, they just have a convenient lookup tool on their site )

Hi Whardison,
Really appreciate your reply thanks a lot. Actually i checked the ip address in blacklist url which you mentioned it gives status ok and is not listed as blacklist.
any other possiblility for such reasons / errors.

Hi Ranjit,
It could be that the site at 203.x.x.x has compiled their own RBL, which isn't publically listed.
At this point, I would recommend contacting the admin or helpdesk of the receiving domain to determine the reason for the blacklisting.
Obviously, if you cannot email them from your own server, this would need to be done by other means; such as phone call or emailing from another site ( hotmail, gmail, etc... )
