Hi tech,

I have a problem, everytime my clients uses his ip 41.79.10.106 he gets the error message 

               The mail system

<>: host [65.55.37.88] said: 550 SC-001
    (COL004-MC2F14) Unfortunately, messages from 41.79.10.106 weren't sent.
    Please contact your Internet service provider since part of their network
    is on our block list. You can also refer your provider to
    . (in reply to MAIL
    FROM command)

Kindly help me delist this from your network.

Hi ,

Based on the error message what i understand is given below.

Remote host (host [65.55.37.88] said: 550 SC-001) is blocking the message which is coming from 41.79.10.106 .

Remote means that is the server at the destination end.

So we need to contact the destination domain administrator to white list your ip address (41.79.10.106) to send emails to their domain.

Hi S.Nithyanandham,

The remote host (65.55.37.88) is the Hotmail servers. How soon can we get feedback on when the whitelist will take place? I am asking this for the sake of my clients..

Hi ,

Known to my knowledge ,You can check with your ISP to get the clarity.

Hi S.Nithyanandham,

We are actually a tier-2 ISP. So is there a Hotmail blaclist that I can check in?
