    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...

    Hi, the goal is to create ready2run/fully installed cloud-init templates for different applications ( like Nextcloud, Owncloud, Seafile, Mattermost, BBB, gitlab and others ). So you will deliver a working cloud-init config, that will install those applications on blank cloud-images from debian or ubuntu. As cloud-init might be limited to build up complex setups, you can support the setup with puppet. In such cases aside of the cloud-init config you will also have to supply the puppet config. Every different Application-Template will have its static price, based on the complexity of the task. We will give you the requirement and we will talk about a pricing for the different Application-Templates. Payment will be immediately after successful testing of your code in our environment. T...
