Your Domain Needs an SPF Record!
If you have recently experienced emails to btinternet.com bouncing back into your inbox then we have a solution for you, and even if you haven’t we would advise you continue to read and take the following action anyway.
A recent change by BT now means that unless your domain (e.g. administersoftware.co.uk) has an SPF (Sender Policy Framework) record, then emails will be refused and will therefore be returned to you!
“Sender Policy Framework is a simple email-validation system designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain comes from a host authorised by that domain’s administrators” – see https://en.wikipedia.org/wiki/Sender_Policy_Framework for further information.
To check if your domain has an SPF record go to https://mxtoolbox.com/spf.aspx and enter your domain name. If no SPF record is found, then we recommend you contact whoever looks after your domain name(s) and ask them to provide the necessary record for your mail exchange. If you are using ours (because details of yours wasn’t available at the time of installation, check Tools -> Options -> Defaults -> System -> Email tab, to see if the SMTP Server is auth.smtp.1and1.co.uk) then request that the mail exchange for 1and1 be added to your domain’s SPF record, which is:
v=spf1 include: spf.kundenserver.de – all
If you require any further assistance, please do not hesitate to contact us.
Many thanks to John Lomas Removals & DC Groves & Son for alerting us of BT emails bouncing back using our mail exchange from within Move Administer.
