Yes, the port 25 is open but our filter limits each server to 5 outgoing smtp connections per minute. In case of abuse (spam, fishing, virus, impersonation, ...) the port 25 will be closed on all of your servers.
VPS and Cloud VPS offer the same capabilities, but the platforms differ. VPS runs on a single server, Cloud VPS runs on a cluster with redundancy.
On VPS, port 25 is closed. Cloud VPS has shared storage and high availability.
We recommend Cloud VPS for professional use or redundant setups. Always implement a backup strategy.
Distributions available with one click: Almalinux, Rocky, Fedora, Ubuntu, Debian, Alpine, Archlinux.
