I have around 25 websites hosted on shared hosting environment. Somebody, who has also hosted a website on the same hosting server started spamming. Due to this spamming activity the shared IP got black listed.
Due the IP black listing and rated as High Risk by some black-listing authority, all the mails sent by the e-mail ids created on my websites are being bounced.
How to avoid these scenario and protect my websites from suffering for the wrong actions done by others? Is there any work around? Is there any technical solution so I can give seamless e-mail communication for my websites?
