Remote SMTP server banner : 220 snubby1-wceast Snubby Mail Rejector Daemon v1.3 readyr
How about a plugin that detects specifically this banner and warns about it? As some people have pointed out in other mailing lists, Verising mail server does not comply with any kind of standards (it justs answers, regardless of what it is feed to, it several 220 responses and then a 500 reject).
It might or might not be relevant since Verisign might desist from breaking up the Internet (indeed, the SMTP server is not available at the moment)
Also, having a plugin that just checked the remote IP address and warned "You might have introduced a typo in the hostname X, you are going to scan Verisign" maybe could be appropiate also.
IMHO it really depends on how long will Verising keep this fuck-up. If they back step in a week/month it's not worth dedicating them a plugin.
