Suppress Invalid Recipient Warning
From Roaring Penguin
To suppress the Invalid Recipients warning:
- - Go to Setup : Verification Servers
- - Enter the domain in question, and use the word "ignore" (without quotes) as the verification server.
This signals to CanIt that you are not interested in a recipient verification warning for that domain.
Note: This option is NOT available for Hosted CanIt as per the terms of service.
