Using external DNS with our email service

DNS records form an important part of both the security and deliverability of email. With this in mind, we strongly recommend using our DNS service (which is included, free of charge) when using our mail service – it is the best way to make sure your mail gets delivered.

If this is not possible then you need to add the following records. The process of adding and editing DNS records will vary from one provider to another, the content of the records, however, is the same.

MX Record

@ 14400 MX 1 servername.netweaver.co.uk

This consists of 5 parts – the @ (or in some cases your domain), followed by the TTL (the time the record should be cached for in seconds), followed by the priority (which should be 1) and finally your server hostname which can be found in your control panel. eg. brown.netweaver.co.uk

SPF Record

@ 14400. TXT. v=spf1 +mx +include:spf.netweaver.uk -all

This is a text record that tells mail servers where to expect emails on your domain to come from. Sometimes you may need to add speech marks (“) around the last part of the record.

DKIM Record

default._domainkey. 14400. TXT. v=DKIM1; k=rsa; p= Long Random Key

To find out the entry for this record, login to your control panel and access the ‘Zone Editor’ menu. Here, click ‘Manage’ and find the relevant record – copy and paste this in its entirety.

Testing your new settings

DNS changes can take some time to take effect, this varies depending on your provider. After a few hours has passed, you can test your settings by sending a blank email to check-auth@verifier.port25.com

You’ll receive a response back with a check on each of your records. If you’ve done it all correctly then it will look like this:

SPF check: pass
“iprev” check: pass
DKIM check: pass

If you have difficulties setting any of these records, please contact your DNS provider for assistance.
