Funny I've started recently getting the same thig also Paul...getting right on my tits...I spendthe first 10 minutes of my morning deleting all of these crap emails.
Mine seems to have started since we opened our website, which has my email addy on for contact...but the messages are never addressed tome...but to joe bloggs et al.
Same as you though...they are addressed to
soandso@myurl.co.uk.
Whats the crack then?
