Well, it's clearly a dynamic IP address, which is a bad sign.   
Legitimate ISP clients *should* be routing their out-bound mail via  
the ISP's SMTP server, so this one is probably a spam-bot.

You can try that, but unless you're really concerned about the  
bandwidth, you can (as I do) go a long way to a spam-free existence  
by deploying bogofilter, a fast bayesian spam filter.  I get about  
three or four thousand spam messages a day, and no more than a dozen  
or so wind up in my inbox.  I've had the same e-mail addresses for  
more than ten years, and they're easy to scrape off the internet.  I  
agree with you that hiding by changing addresses isn't a very  
satisfactory solution.

Cheers,

Andrew
