Note that the 'Default Forward' blank is automatically set to the E-Mail address you supplied when you signed for you account. You may find this useful if you get many requests for the same information. It must conform to the same rules that receiving addresses in the Mail Forwarding section obey. There are several ways in which to specify the content of your auto-responder. However, with the third option, when you specify a file in your home directory, it allows you to upload a message containing any headers that you want.
Headers end with an empty line, and everything that follows is interpreted as the body text.
Once you upload the auto-responder text correctly, the caption should stop blinking. You may even do this for your Default Forward. Spam is the unsolicited or bulk e-mailing of advertisements and the like. Spamming is highly frowned upon throughout the Internet community, and we are no exception. Because of this, we have a strict anti-spam policy in our Account Usage Agreement.
