The user has stopped using their gmail address, and has gotten a custom domain hosted by another provider. They have the old gmail set up to send an auto-reply to mail still sent to the old gmail address. This message says "I have a new email address - please use email@example.com"
The user would like to make sure that the auto-reply isn't sent to any spammers.
Does gmail send auto-replies to the messages that it filters and files in the Junk E-mail folder? If so, is there a way to route the mail and send the auto-reply after the spam has been removed?
