Hello All guys,

he send almost 12,000 emails in 1 day. after that case, my server main IP is listed in SpamHaus CSS Blacklist.
i contacted to the them but they refused to delist our IP. and after some days my clients domains are now going to spam list in spamhaus DBL becuase the IP to whom they're pointing is also in CSS Blacklist. and after 1 day, .xyz and .online domains are suspending and going on serverHold because of they are listed on spamhaus.

and now a days, whenever any client purchase hosting with .xyz and .online domain and set my nameserver then after some hours his domain is also going on serverHold.

If you have an extra clean IP address on your server then you can route your emails through that IP address by setting it up in /etc/mailips

How to Configure the Exim Outgoing IP Address | cPanel & WHM Documentation

To decrease the chance that spam filters mark your mail as spam, verify that the reverse DNS (rDNS) entry of Exim's outgoing IP address matches the DNS response of your server's hostname.

Note: You need to make sure first that no more bulk emails are being sent from your server, else you might end up getting your other IP address blacklisted.

You should detect spammers and stop them from sending, in the first place.
Then you can request delisting from SpamHaus blacklist. This can take a few days. In the meanwhile you can adjust the e-mail sending limits in WHM in order to avoid this to happen again.

I have added Limits into every package of my server one by one and also changed SMTP Server IP Few Hours Ago.
But IP is listed from more than 1 week, after 1 day of listing I already detected the user who is doing spam and suspended that and also added limits into packages but still SpamHaus didn't delist my IP.
