My logs show a number of SMTP protocol violations similar to this one: 2005-11-21 04:55:24 SMTP protocol violation: synchronization error (input sent without waiting for greeting): rejected connection from H=ns1.avs18.com[85.118.32.254] input="POST / HTTP/1.1\r\nHost: projectile.ca:25\r\nContent-Type:text/plain\r\nContent-Length: 891\r\nMax-Forwards: 10\r\nVia: 1.0 projectile.ca:25\r\n\r\nRSET\r\nHELO lab-"
Does anyone know what the deal is with those? Is it some kind of exploit against a broken HTTP proxy server? If so, why is it hitting port 25 instead of port 80? - Marc -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
