I have had some biz folks freak out when I used bigcorp@mydomain.com, they just couldn't grok how that wasn't like joe@bigcorp.com. So I now just use a generic term, but unique for each site. With a catchall on the mail routing I still get to see them all. Really easy to then auto-delete those who sell my address to somebody else. Also use unsubscribe option on a lot of newsletters, etc that I am no longer interested in. For the most part, they seem to work. If not, place them on the ever growing black-list.
