Bigfoot email problem

[#1]

I use a Bigfoot.com email adress forwarded to my plusnet account . For about a week now I have not recieved any emails at all. I have searched for  reports/discussions about current problems with Bigfoot and found none. Last night I ran a test by sending myself an email to my bigfoot address from Outlook  and got the following error message.
Any ideas please?

It looks like the bigfoot email servers have got 'poor' senderbase reputations ( http://www.senderbase.org/senderbase_queries/detaildomain?search_string=bigfoot.com ) due the amount of spam originating from them,  and therefore the email from them is being blocked by the PlusNet Ironport system.

Solution would be to turn off spam filtering on your Plusnet account (as long as you don't mind the obvious implications that come with it!)
