Validating e mail
It is a non-statutory body comprising representatives from higher education institutions and other related organisations in the United Kingdom.
To advance education, including training and research, in particular by: The CVU defines ‘collaborative provision’ as the process whereby a degree-awarding body judges one or more programmes of study, courses, or modules offered by another body to be appropriate to lead to a qualification and/or credit of that degree awarding body.
You can also use the third test in the validator to experiment with different IP addresses your mail might come from with different records and see that you get the results you expect.
The first two tests can tell you if the syntax of your record is correct.
You should always retain a copy of your tax return.
First, if you have an existing SPF record (or if you don't know if you have an existing SPF record), go to the validator and enter the domain name part of your e-mail address (everything to the right of the symbol) into the topmost box and click on "Get SPF Record (if any)".
That will tell you if your domain already has an SPF record and if its syntax is correct.
If you don't know how, you will need to contact your DNS provider.
If you don't know who that is, it is probably the domain registrar that you registered the domain with.
