After using VMWare ESXi for a long time as a Hypervisor for my virtual servers I decided to stop paying OVH for that service and I migrated my virtual machines to VPS servers on OVH. At the end of the day only two VPS with a cost of 3€/month are enough and I can stop a 50€/month dedicated server.
The biggest challenge that I had to solve was migrate mail server to a new server. So far today I was using pfSense a firewall for my virtual servers. They were in a virtual network; pfSense anti-spam services and mail forwarding were enough to receive “cleaned” mail in my private mail server with Postfix and Dovecot.
New configuration is just a cheap VPS (1xCPU+2GB RAM+10GB SSD) with Ubuntu 16.04 and also with Postfix and Dovecot. But I decided to rent the anti-spam, anti-malware and anti-virus service to MX Guarddog. I discovered that service just surfing on the big G. Only 0.25 cents per account per month it’s a very good price and it does all the things that I need and much more. Configuration is really simple if you know what you are doing. They have a very good and simple control panel to manage the service. This is the perfect service to get what I need.
In the control panel you can do all that you need, manage mail accounts and domains. View quarantined mails and all required configurations and tests to validate everything is ready and also maintain white and black lists. We’ll see during next days if the service gets the quality that I expect, I hope I have found a very good and cheap resource.
