If I don't want to buy a server with you and I just want you to install PowerMTA on my server, is this possible?
Yes, this is totally possible. It is one of our service. It is the Installation service. So yes, we can install PowerMTA 5.0 on your server and configure your IPS, RDNS, DMARC, DKIM, SPF. And even if you want we can warm up your IPs. This is an optional service.
