Port 25 is blocked on Dedicated Servers
In order to protect our IPs from getting blacklisted and to prevent abuse on our network, we have blocked outgoing email for port 25. As a better alternative, we offer Smarthost. This is a Free Outgoing Spam filter service that will allow you to send clean emails. For more information regarding our SMPT relay service take a look at the link below:
Port 25 and Port 5060 are blocked on Dedictated servers and Cloud VPS
We have also blocked outgoing email for port 25 on our VPS servers. Port 5060 has been blocked recently due to ongoing SIP brute-force attacks originating from our network. Hence, Outgoing traffic on port 5060 tcp/udp has been blocked for our VPS platform. If you are running a legitimate service requiring port 5060 outbound we can make some exceptions for your service. You can send an email to email@example.com with your requirement and after we have reviewed your email we can enable the port on your server.
