No doubt.. It's unfortunate that they are running a daemon on port 25 on that box.. and that it actually lets you helo and mail from.. and not until you get to rcpt to does it reject.. unless you use a domain its now got cached in which case it accepts the to: and closes at data. (So, if you rcpt twice, it'll accept it.. cuz like everyone else, its own dns server resolves everything) [[email protected] netmask]$ telnet www.oisdufoisdufoisuf.com 25 Trying 64.94.110.11...
