Hi, for some reason our servers from 126.96.36.199-107 are getting blocked by the email service and no emails are being delivered.
None of the IPs are listed on any other blacklist so I wonder if this is a false positive. All emails are legitimate email servers.
This is the error I get:
- The host has been observed sending spam in a format that is similar to snow shoe spamming techniques.
How can I get them removed permanently?
I remove them and they get listed again.
Thanks much in advance,
