If you didn't munge the IP address we'd be able to read the URL you were given. As it stands, yes, it appears SORBS is listing 205.196.xxx.xx.
In my experience, most ISPs won't waste their time dealing with SORBS, as they don't remove hosts from their "spam database" without a $50 fee, which is tantamount to extortion. Your best bet is to have the intended recipient complain to their ISP/hosting company/sysadmin for using this list in the first place. If this fails, try using a different SMTP server.
If you want useful replies, ask smart questions.
