Hi LKing, Thank you for your reply. I gathered these IPs from our Cpanel's tracking delivery logs. Since I'm in charge of IT, I was required to figure out why the messages from the contact-us form didn't reach the email under our domain which as a result led me to the Junkmail/Spamcop logs. FYI, if we were to send emails to that particular email from other emails(private/public), they will be delivered as usual. Meanwhile, if we were to use the e-commerce platform, it will utilizes sendgrid's platform to make the deliveries, which in turn, those messages will not go through. So the email/messages didn't reach only via the e-commerce platform. So, I'm still stuck to be honest... On the spamming part, I hope its due to us trying to send hundreds of test messages to the email somewhere last week, nothing else. Hi gnarlymarley, Thank you for your reply. Well, that's unfortunate to hear. I did a tracert to that IP, it belongs to sendgrid's. So maybe it was due to someone using the platform maliciously.
Hi Support Team, We are using the CPanel platform and we encountered the issue of not receiving emails from some IP's addresses. Basically, we are trying to launch an e-commerce web platform soon and there are several text-based forms that are linked to our domain's emails vis sendgrid's DNS. Thus, we tested sending test messages on huge number of times. Initially, most of them were unsuccessful due to sender verification problems, then we managed to fine tuned the DNS settings. Now it seems the verification problem is solved instead the only error now are along the lines of 'JunkMail rejected - xtrwkkxd.outbound-mail.sendgrid.net [188.8.131.52]:58332 is in an RBL: Blocked - see https://www.spamcop.net/bl.shtml?184.108.40.206" Other IP addresses are 220.127.116.11 18.104.22.168 22.214.171.124 spam reasonings were: "Causes of listing System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop) SpamCop users have reported system as a source of spam about 20 times in the past week" Please assist us to unblock those IP addresses. Thank you.
