So what makes a spammer want to use a valid email address as a return or reply-to address to catch all the undeliverable, failure and bounced email that occures when sending UBE spam. Is there some legitimacy with spam detection on an email that contains a valid reply-to email address? To me, spam is one thing, but loading a mailbox with literally several thousands of bounced emails is abusive. I'm lucky as I have the option to click one button and remove them all on the server, but for a user to have to delete individually or as a group after downloading them all is just wrong. Any ideas on preventing or minimizing this type of spam? Thanks. Wes
