We set this up in customer accounts by going to cPanel –> Email –> Authentication. How to enable SPF and DKIM records in cPanelĬPanel do not enable SPF & DKIM by default. It can result in the mail getting tagged as spam if the email content has spam like content (links, flashy images, etc.). If there are no SPF or DKIM records defined, receiving mail servers will have work with the assumption that the sender may be fake. Receiving mail servers use this to check if an incoming mail is valid. SPF and DKIM records list the authorized mail sending IPs for a domain and decryption keys for encrypted headers. Mail servers fight against this by using DNS records called SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail). Spammers often use fake “From” email IDs to make customers click on a phishing link. This will complete the full DNS loop, and many service providers consider this as an indicator of a well maintained mail server. The server name will point to the IP assigned to the server.The mail server IP will have a PTR record pointing to the server name.So, we avoid this spam score by setting up FCrDNS, which means: Many mail services providers (like Hotmail) use this as an important indicator of spam source. These servers and PCs usually have a sloppy hostname and an IP that doesn’t have a PTR record. The vast majority of spam mails are sent from infected PCs or poorly maintained mail servers. Setup FCrDNS (Forward Confirmed Reverse DNS) To prevent mails from being tagged as spam, we need to boost the “not-spam” signals, and cut down possible “spam” signals.ġ. Mail servers mark a mail as spam based on “spam” and “not-spam” scoring. How to prevent cPanel mails to go into spam folder So, large mail providers err on the side of caution and mark a low spam score email as spam. We’ve seen that some mails, while legitimate, produce a low spam score because of the poor reputation of the server IP network, message encoding, message headers, etc. This includes IP reputation check, message composition, RFC compliant SMTP handshake, mail user feedback, and more.Īll these checks together produce a spam score that determines whether a mail is spam or not. Mail servers use a wide array of anti-spam checks to keep out spam. What causes cPanel emails to land in spam folder? So, why do cPanel emails go to spam folder?
There would be no apparent explanation for this.
Here at Bobcares, we help cPanel users fix such issues as part of our Outsourced Tech Support services for web hosts & digital marketers.ĬPanel users complain that even after they’ve enabled spam checking, box trapper, authentication, and more, their business mails still land in the spam folders of Gmail, Hotmail, etc. That can be quite aggravating when you’ve paid good money to setup anti-spam checks and whatnot in your cPanel hosting panel. But your mail lands in spam folder anyway.
