Unmanaged SMTP relay for sending Email:

Relay SMTP access is granted only for email sent using Blucom internet connections and does not require a username or password, this is an unmanaged service and faults regarding email failure are not supported.

The relay domain addresses are:

  • relay.ukdsl.co
  • relay.voicehostdsl.com
  • relay.newbreedbb.co.uk
Speed Test Servers

Speedtest tools calculate a snapshot of the connection speed to our network AS31472:

  • Download – The maximum currently available bandwidth downstream
  • Upload – The maximum currently available bandwidth upstream
  • Ping – <150 ms is preferred for QoS
  • Jitter – <30 ms is preferred for QoS

You should ensure that no other devices are using the connection during the test and you are connected directly into the primary router.

Reverse DNS and SPF:

Reverse DNS is IP address to domain name mapping – the opposite of forward (normal) DNS which maps domain names to IP addresses. Please contact support if you require reverse DNS as you may require this in order to send emails and have them accepted by other networks.

Sender Policy Framework (SPF) is an email validation system designed to prevent email spam by detecting email spoofing, a common vulnerability, by verifying sender IP addresses. If your domain does not have an SPF record, you will also need to add this as some recipient domains may reject messages from your users because they cannot validate that the messages come from an authorised mail server.

Additional IPv4 addressing and IPv6:

Subject to approval based on RIPE guidelines and RFC2050 (Section 2.1), Blucom can offer additional static IPv4 subnets to its broadband customers on all products.
Please contact support for further details.

IPv6 is disabled by default but can be enable IPv6 via your account control panel.
