DEAR generates emails to send to customers. If your organisation is using a custom domain to email customers, DEAR emails can be flagged as spam by the customer's mail server and not appear in a customer's inbox. This is resolved by adding a line to your organisation domain's SPF record. SPF is a mechanism the recipient mail server uses to verify if the DEAR domain (@post.dearsystems.com) is allowed to send a email behalf of another domain.
You will need to add this line to the custom domain SPF record:
When this is done, the email will not be marked as spam by the recipients mail server.
We also recommend whitelisting the following DEAR IP addresses:
- DEAR Inventory IP address: 220.127.116.11
- DEAR Inventory mail server IP address: 18.104.22.168 & 22.214.171.124
The whitelisting of the mail server IP address is particularly helpful in case you're not receiving any emails from DEAR, which may have been dumped to your mail server's spam folder all the while. If you are unsure about how to go about whitelisting IP addresses, kindly seek your hosting provider's support.
