Port 25 is closed, what to do
Edpnet blocks all traffic coming from dynamic IP addresses via port 25, except to our relay server.
If you use edpnet connection and a dynamic IP address, you should check an outgoing server name in your mail program. A correct one is relay.edpnet.be. It’s only possible to send mails via this relay.edpnet.be server. Following link may be useful: Outlook Express configuration
If you are using a dynamic IP address and your own mailserver, you should adapt your server configuration in the following way: MS Exchange server on dyn ip
If your IP address is dynamic and you are sending mails via another (for exemple, your employer's) outgoing server, you may:
- replace outgoing server name by relay.edpnet.be
- use VPN connection. Your employer can configure it for you.
