Could you please ensure the access rule that you created to allow port TCP 25 from LAN to WAN is set to top priority? As @MasterRoshi said, please share the drop reason of the packets which can be obtained from Packet Details section in the Packet Monitor page to figure out.

Hey @Dave_Loveridge, can you paste the drop code from the packet capture? It should show when you click on the drop entry at the bottom.
