When you are using SharePoint in combination with SSL and Send To locations you have to register you certificate with SharePoint when you would like to register a Send To location that runs under a https address.
When you try to add the location you will receive the following error:
Verification failed: URL is not a valid routing destination.
You will also find a entry within your event viewer which let you see what certificate you need to register:
