Outlook.com is blocking all email sent from this IP.

Hi Guys,

 

I'm having trouble unblocking my mail server from sending email to any Outlook.com Related addresses.

 

I have found that the problem is due to various users attempting to send mail to accounts that have never/no longer exist. This has now been stopped and I'm now looking to unblock the servers IP to allow my users to send to Outlook.com related addresses again

 

I have had a look around and I can't find any details on how to apply for this to be done. I have setup a SNDS account for the server IP and can see that it's blocked but there isn't much information on getting it allowed again.

 

Any information that could be provided, links, would be greatly appreciated.

 

Many thanks,

Martin.

My server is still blocked by hotmail.com (550 SC-001)

Hello,

my mail server currently got a problem with sending emails to hotmail.com accounts. My server ip was flagged in spamhaus.org database for not sending a correct header. I think this lead to this problem. But my ip was removed like 1 month ago and I still receive messages that my mail can't be sent.

Error code is 550 SC-001 Unfortunately, messages from xx.xx.xxx.xx 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 http://mail.live.com/mail/troubleshooting.aspx#errors.

Is there something I can do to resolve this problem?
Sorry for double posting this (in an old discussion and my own one, didn't see how to create a new discussion)

Best regards
