How do I add an email address as an approved sender in Postini?
Log in at http://login.postini.com using your email address and email password.
- Click the "My Settings" link, then Block Senders.
- Add specific email addresses in the Blocked Senders box. If you're being pestered by a vendor (as opposed to an out-and-out spammer), you may want to add the vendor's domain under 'Blocked Domains' to stop all mail from them, even if they change part of the return address.
Note: blocking senders and domains will work to block mail from specific people or domains, but it won't help much with routine spam, since spammers usually forge the return address and change the return address every few minutes.
