Or a site running qmail, sending to you with lots of recipients. (Qmail seems to like to open a new socket for each recipient instead of just doing multiple RCPT TO's.... Maybe that has been fixed, but I doubt it... I think they call it a feature... some of us would call it a feature when Anvil blocks such silliness... the case I saw here was someone sending 10M files to 100 recipients... 100*10M instead of 10M just once.)
