Velocity MTA can run on unlimited remote servers.
Velocity MTA has its own license and can run on unlimited remote servers that all point back to one emaildelivery.com ESP platform installation.
Velocity MTA can run on the same server as the ESP platform.
However, Velocity MTA needs to run on a different ip address than the ESP platform. Find more information on the explanation behind this limitation .
To install and configure the MTA you'll need to familiarize yourself with the following concepts in advance:
Check out some YouTube tutorials if necessary, once you have the ability to connect to a Linux VPS and edit text files, our documentation will give you the exact commands you need to run, so there won't be any missing information that prevents you from completing your MTA setup and configuration.
ChatGPT knows Linux better than any human and is a hugely underrated resource for all Linux questions, technical questions about email delivery, and all of the topics applicable to an MTA.
You'll need your IP address and root password from your server hosting provider for this next step.
Don't copy and paste this exact command, it's just an example using a placeholder, 1.2.3.4 would be the IP of your own server here.
SSH into your server where the IP addresses to be used with the MTA are assigned:
When you enter your password you won't see anything on the screen.
This is normal. Your root password isn't shown so that someone looking over your shoulder can't see it.
Once you've successfully authenticated as the root user you'll find yourself at a prompt that looks something like the below, which will be slightly different for each server provider.

Paste the download link from your AppSumo portal into the command prompt on your Linux server:
The below is only an example, you need to use the real download link from your own AppSumo portal.
This will download a file called velocity-install.tgz onto your server, you should recognize this process from when you installed the ESP platform previously.
To extract the Velocity MTA archive run the following command:
You should see output similar to the following:
Velocity MTA is self-contained within one directory called velocity-install, similar to the ESP platform.
Change directory to velocity-install:
The mta.defaults.conf file exists so you can 'start over' with a new properly formatted mta.conf file as a troubleshooting step.
Now you're going to need to edit the mta.conf file with nano, a popular Linux text file editor:
There are only four settings in mta.conf:
The Management IP is NOT the IP of your ESP platform, it's the IP of the server you're on right now where you're doing this MTA configuration.
The Management IP can also be used as a sending IP.
Save your mta.conf file changes, remember to watch a tutorial on using nano in Linux if this is unfamiliar to you.
Now you need to tell Velocity MTA which IP addresses are available to use on the server for sending email by editing the conf/ipaddresses file:
The format for the conf/ipaddresses file is dead simple: one IP address per line
Make sure extra IPs are configured on your server, not just provisioned to your server.
When your server hosting provider provisions you more IPs, they don't automatically "just work" on your server. Someone has to enable them in Linux once they've been assigned. ChatGPT can tell you exactly what to do here, or you can try opening a ticket with your hosting provider and see if they will do it for you, if all else fails there's fiverr. Don't ask us, we'll just ask ChatGPT and tell you what that dude said.
Save your conf/ipaddresses file changes, remember to watch a tutorial on using nano in Linux if this is unfamiliar to you.
Now you need to tell Velocity MTA which domains to accept email replies for by creating a list of receiving domains.
Do this by editing the conf/receiving_domains
The format for the conf/receiving_domains file is dead simple: one domain per line, including subdomain if applicable:
Save your conf/receiving_domains file changes, remember to watch a tutorial on using nano in Linux if this is unfamiliar to you.
Next, you'll need to install Docker if you're not using the MTA on your ESP platform server.
As part of the ESP platform install process you installed Docker already, so this step wouldn't be necessary in that case.
We've included a script for automating the Docker installation process on Ubuntu:
Now that Docker is ready, load the Velocity MTA Docker Images:
You'll see output similar to the following:
Finally, start Velocity MTA:
Verify Velocity MTA started properly:
Check the log file:
Velocity MTA is running!
You'll need to add your new Velocity MTA server to your ESP Platform to start sending email.
Log into our AppSumo portal where your download links are at
The Management IP is not "reserved", it can be used for sending email with the MTA. However, when run on the same server as the ESP platform, the Management IP must be separate from the IP being used by the ESP platform due to reasons explained in our documentation.
