Can we bypass sender base lookup by recipient address

Dear

      Can we bypass sender base lookup by recipient address

      for example, if the email to send to 123@cisco.com, let this email go through, I know we can set white list to filter e-mail by sender, but how to filter by receiver?

HI,

We may need to confirm in a bit more detail what the final objective is here.  SenderBase is used to score the IP address of the sender only. If you have someone your trying to get mail to , that is not getting it due to a poor SBRS score then one option would be for the recipient domain to whitelist your IP. Whitelisting is probably the least desirable option so it would be worth looking a bit further into exactly why the messages are getting dropped. One possibility is that the recipient domain has specific HAT settings that force the senders IP into a custom range. The other possibility is that the senders IP (your IP) has a poor score so you may wish to check the score for your IP.
