Its a junk email

1) The "scam" would actually form a telecommunications fraud not a royal mail one.
2) you cannot be charged £15 for a call by connection only - the max UK rate is £1.50 per minute - if you hang up straight away you only get charged £1.50

The Royal Mail number is/was an INTERNAL FRAUD number. It was at one point being jammed and may now have been removed.

ICTIS actually have this to say about the scam AND THEY CONFIRM THE EMAIL IS A HOAX (although it relates to an incident in 2005 - which has now been closed down). http://www.icstis.org.uk/pdfs_news/email.pdf
