How is sendmail supposed to be able to listen on an address that your 
computer does not have an interface for? How is the public IP address 
associated with this server?

How is your VPN connection established? Is it there all the time, or 
created on demand?

If you don't specify an "Addr" parameter, sendmail will listen on all 
interfaces, and should accept connections from VPN interfaces as and 
when they are established.
