Although it may be true that some web servers might not like the envelope sender that isn't your main problem. If your ISP is flash.net you need to use their smtp server. If smtp.freewwweb.com would relay mail for anyone who put their return address as [EMAIL PROTECTED] then they'd be a spammers heaven. smtp servers only relay (if they're properly configured to reject spam, as all servers should be) from hosts that are "local" to them which generally means hosts which are part of their (or their customer's) network. If you're connecting through flash.net just use flash.net's smtp server to send mail. It won't care what your return address or envelope sender address is.
