Windows Outlook Express

[Gunaa]

Hi,

I got one error on Windows Outlook Express, it was not continious problem it will be after 5 hours or 6 hours after it comes, sometimes it work properly.

Also I pasted the Error while send the mail to my collegues.

Error Message :

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'nmaran@kaar.in'. Subject 'Discussion', Account: 'Kaar Technologies', Server: 'mail.kaar.in', Protocol: SMTP, Server Response: '451 http://www.spamhaus.org/query/bl?ip=219.64.184.139', Port: 25, Secure(SSL): No, Server Error: 451, Error Number: 0x800CCC79

Waiting for proper solutions.

IP Address Lookup

219.64.184.139' is not a valid IP address.

If the IP you are checking is not in our database, but you are receiving bounce messages saying it is, then it is probable the IP has been removed from our database but DNS servers around the internet have not yet updated. In this case, wait 1-2 hours and the blocking should clear by itself.

This tool is for manual (non-automated) lookups only. Any perceived use of automated tools to access this system will result in firewalling or other countermeasures.

MAYBE THAT IS THE PROBLEM???????????
