How do I enable the outgoing mailports on my VPS?

With the launch of our VPS mailcluster (carefree mailing) we have disabled the outgoing mail ports (25, 465 & 587) by default. More information regarding the specifics can be found here.

Is it possible to open these ports?
This is most certainly possible! For security reasons there are 2 requirements:

  • You will first need to set reverse DNS for your VPS. An example of this is Do not use 'generic reverse DNS' such as something containing the IP-address. That would result in increasing the chances of your mail being stopped as spam.
  • Another requirement is that at least one invoice has been successfully paid from your account. For this second requirement a default period of 17 days is maintained (as an invoice can be bounced, a payment error could occur, etc). This means that only after 17 days have passed can you open your mail ports or request our support department to open them for you.

When you meet all requirements, you can enable the outgoing mail ports in your control panel by following the steps below.


Step 1

Log in to your control panel, navigate to the 'BladeVPS' tab and click the name of your VPS.


Step 2

Under the VPS-console you'll find the Network overview. Enable the mail ports by clicking the switch behind 'Outgoing mailports'.

Certain checks will be started in the background. Once complete, a notification will be shown and when you scroll down you'll see the switch now shows 'On'.

If the checks were successful, you can immediately start mailing from your VPS using the mail service. If you receive a notifications that some requirement is not met, please recheck if you have successfully set all requirements and try opening the ports again.

If you are not (yet) able to comply to all requirements, but do want to have the mail ports opened because you (for example) use another external relay, you can send a message to our support department. After receiving that message, we can look into your specific case and manually open the mail ports. Please note however that the 17 day period requirement also counts in this situation.
