I keep getting reports from users trying to send mail in from gmail that they are getting bounce messages that Zimbra is rejecting their email due to a Sorbs block.

We had Sorbs in our RBL list but removed it a long time ago due to issues w/ good emails addresses being blocked.

I've tried whitelisting the addresses and verified Sorbs is no longer in the RBL config so why / how is it still able to show up like this?
