IP Address Lookup


*****is not listed in the SBL

***** is not listed in the XBL



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 lookup 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.

as per the xbl website my server ip is not listed and it might take 1 to 2 hours to update DNS server around the world. but im getting bounce mail since week or more than that..

i am able to send a mail to those email account using yahoo or hotmail or gmail.


what should i do now.. thank in adv.
