My IT provider informed that my IP 188.8.131.52 (Type A) was added to black list. As my provider explained it was problems with email performance.
I got answer:
You need to contact your Internet Service Provider (ISP) or hosting
Requests to remove an IP address from the Spamhaus Block List (SBL)
must be made by the Internet Service Provider / hosting provider who
owns the IP address (see SBL Advisory page).
Please note, as this is an unresolved and ongoing issue, SBL445079 is
currently ineligible for removal from the Spamhaus SBL zone.
Please contact your ISP and inform them of this SBL listing. It is
possible that your ISP does not know about this SBL listing, or does
not realize there is a spam issue with a customer in this IP space, or
possibly your Internet Service Provider has not understood that
Spamhaus is waiting for them to contact us when they have terminated
the issue detailed on the SBL record page.
Could you please fix it?
