wryghta Posted April 19, 2005 Share Posted April 19, 2005 Hi, I just wondered. Does any spammer EVER filter a list to remove dead accounts? My SMTP server can terminate an RBL flagged connection by responding to a RCPT to with a "User does not exist" code. But if spammers ignore this - what's the point? I noticed that I am getting about 500 RECPT TO unknown "accounts" at my domain every hour. So either spammers are doing random account tests, or some email lists are 99% random names before they are sold. Any thoughts? Link to comment Share on other sites More sharing options...
