You know....
Someone needs to come up with a new, better, standard for sending emails. Something that includes some kind of checks and balances to verify that the sending email address actually belongs to the user sending the email.
Some JERK is using one of my email addresses as the return email on massive amounts of span s/he is sending out, and I am having to deal with all of the Send Failure message. I simply can not stress how annoying this is getting..
