I've been using Xeams as my edge MX server for several years. I'm in the process of implementing a cloud SMTP service for inbound email. The service is configured to send all mail to my IP address for Xeams. I've followed the instructions to add the IP addresses for the new edge IP's into the config/gateway.dat file and restarted Xeams as instructed. When I send email through the new service, all my email shows the IP address of the cloud provider instead of the actual sender IP. SPF verification fails on all incoming mail with this configuration. I tried renaming the gateway.dat to Gateway.dat since Linux filenames are case sensitive and that didn't have any effect. Has anyone had any success in defining your gateway IP addresses with this file? Any help would be appreciated.
