I have a webserver that sends emails to my organization based on a web form. Since installing Hexamail those emails are blocked. How do I fix this?
Hexamail only allows authenticated users, internal IPs or listed IP addresses to send internal emails. This is a vital measure to prevent spoofing of emails (which many email servers simply allow!). To enable Internal emails being sent from a nominated external IP address, simply add the IP address (range) to the SMTP Server/Relay/Allowed relay from list.
