Is the Port for Mails (SMTP) blocked?

Stop the Spammers!

---

Unfortunately, the targeted sending of spam emails is a significant problem among cloud providers. To counter this as effectively as possible, we at ST-Hosting block outgoing traffic on ports 25 and 465 by default on all vServer servers. This precaution is widespread among cloud providers and helps prevent the abusive use of these ports. Before we unblock these ports for new customers, we want to build a certain level of trust. However, once you have been registered for at least one month and have at least one active product with us, you can open a ticket for a specific use case to request the unblocking of ports 25 and 465. In your request, you can describe your case and provide additional details. Each request will be reviewed individually.
