It has recently come to our attention that some individual or organisation has been using this domain (filofox.com) in unsolicited email promotional material ('spam'). The 'from' address of these emails is usually something along the lines of 'kxgws@filofox.com' -- ie. a random sequence of characters.
These emails are not, in reality, being sent from this domain: the sender is faking the 'from' address (a very simple process) in order to have the email appear to come from a legitimate domain. Unfortunately we have no recourse in this situation: it is not possible for us to prevent someone from using our domain in this way.
Our best advice is to ensure that your email provider has implemented some sort of filter to block this sort of unsolicited bulk commerical email. If this is not an option, you might consider using one of the many personal spam filter programs available.
