E-mails sent from a Hypernode are marked as spam
Troubleshooting mail from Hypernodes
Check SPF records
Check if the spf.appname.hypernode.io hostname is included in your SPF record (in the DNS zone-file). This hostname contains the IP-address of your Hypernode and the IP-addressess from Byte’s e-mailservers.
More information could be found here:
If the IP-address from your Hypernode is not included in this record, please send an e-mail to email@example.com, so we will fix the record for you. This could happen after an up- or downgrade of the Hypernode plan.
Check if the return-path is configured correctly
If you send your e-mails using a PHP script, the default return-path will be firstname.lastname@example.org. This e-mail address will be seen as possible spam address, so you have to change this into something else (e.g. email@example.com) or change it into the e-mail address you also use in your Magento installation. We would advise you to use a valid e-mail address which is working! If the recipient is using SAV (Sender Address Verification), and the e-mail address is not reachable, then a spamfilter could see this as a spam message.
Check if your Hypernode is listed in a blacklist
Browse to MXToolbox and fill in the IP-address of your Hypernode to check if the IP-address is listed on a blacklist. If it is listed, you could request a delisting by yourself. Do not forget to check the reason why the IP is listed and fix it to prevent this from happening again.
If e-mails sent from the Hypernode are still marked as spam, please send an analysis request by e-mail to firstname.lastname@example.org including a full-header of a marked message. We will investigate the reason and send you a reply with more details.
