Emails from domains being sent to spam folder

[syzygy66917]

Hi,

For the last few weeks a user on one of our supported/hosted domains has found that emails from her to btinternet.com recipients have been ending up in the spam folder.

I've checked the message headers and the only thing that indicates it is spam is;

X-RazorGate-Spam: true

Does anyone know anything about Razorgate (a Google search comes up with the ir company website, but they won't asist me) and how I can stop it registering the mails as spam?

The full header is as follows;
