Perhaps you have your own preference on Spam control and would prefer to use an alternative service -- you'll want to ad an exemption in Barracuda.  

  1. Login as Administrator here:   (This assumes you have Administrator rights)
  2. Click Inbound settings
  3. Click Recipient Polices
  4. Click Add
  5. Enter Email address
  6. Select Exempt 
  7. Click Add

Exempt (whitelisted) recipients bypass spam scoring as well as all other blocklists. Virus scanning still applies.
