Since installing Hexamail users outside my network cannot send internal email using our mailserver. What can I do?
Hexamail tightens your email security and adds spoofing prevention: this stops external IP addresses sending emails that appear to be internal. This helps prevent SPAM attacks and spoof emails being sent. In order for your users who are outside your local network to send emails you need to: -Add their IP address to the SMTP Server/Relay/Allowed IP list (Does not work if they are on DHCP) -Add a login to the SMTP Server/Security page and then configure the user's email clients to use authentication with their outbound email server settings -Turn off the spoofing prevention in SMTP Server/Relay. There is a checkbox restricting the sending of internal emails to the listed relay IPs or authenticated clients
