SpamCop is blocking the emails sent through sparkpost <p>I am using laravel with the famous and popular laravel framework. </p> <p>I sent a couple emails to my gmail address and a clients email address, I received all of them. A client complaint that he didn't receive them, so I looked it up and saw this in </p> <p>550-"JunkMail rejected - mta65a.sparkpostmail.com [54.244.48.142]:58459 is in 550 an RBL, see Blocked - see <a href="http://www.spamcop.net/bl.shtml?54.244.48.142" rel="nofollow noreferrer">http://www.spamcop.net/bl.shtml?54.244.48.142</a>"</p> <blockquote> <p>SpamCop's blocking list works on a mail-server level.

I guess all mail services have the exact same problem</p> <p>what can my client do about this?</p>
