IMO, DKIM is not worth the time or is it as widely used as SPF/Sender ID. SPF configuration can/may get you blocked, but not necessarily increase spam folder receipts. Don't count on the receiving server to have their SPF setup properly. Depending on how you create the SPF records, can defer the message for additional filtering.
Keep the SPF as short as possible, helping the large and very busy mail providers from spending to much time pinging DNS. Is your DNS service in good working order? Do all your end users always use your SMTP, or can they use other mail servers to send mail in behalf of the domain, e.g, Blackberry BIS? Frank Muto President FSM Marketing Group, Inc.

Fix that problem and move on with the next. I'd be willing to bet with just a few site removals a lot of services get restores - few big ones out there I can't remember what they're called. Have you watched the outgoing SMTP to make sure something isn't hijacked? Send me a message with a new domain, IP, etc and see if it gets marked as spam.
