    PHP Script Email configuration 4 dní left
    OVĚŘENÉ

    I am using WHM Exim for email server. When I send email from PHP script, it goes to spam simply because of a few things: 1. sending domain instead of the actual domain, it uses the server name or domain 2. envelope-from: instead of the actual from address it shows server domain 3. Signing domain is the server domain and not the from address domain name This is the results / source for message sent from webmail: This message was sent from PHP Script https://www.mail-tester.com/test-d17kzwcc5&reloaded=1 I believe if PHP/Exim uses actual from address and not cpanel account name as sender, then the issue would be resolved.

    Install and customize Envoy Proxy on our physical server. This server will run LXC containers that will have 2 ports (per container) that require an active proxied ssl secured location. One of the two ports will require an authentication layer, JWT, to connect to it (Push Websocket). The other websocket (Main Websocket) has its own authentication and should have its route without authentication from envoy. An ideal setup is where there are no outside ports used by the proxy: i.e., and, local ports used in the container become irrelevant. Since if the proxy goes directly to the lxc containers' bridge NAT location, unique port labeling would not be required to avoid 2 websockets broadcasting on the same port. Containers will be actively created/destroyed on the EWS (Enterprise We...
