In that case it really is openvpn related and is a matter of routing. 
Your ISP forwarder will be doing the same IP range test to permit access 
that your one server would do, but you probably aren't routing the 
connection to that server and NATting it so it appears to come from the 
address range the ISP knows.  One way to accomplish this would be to use 
your own sendmail as a forwarder that then forwards to the ISP. 
However, since you mentioned a 3rd party mail provider, before you 
change anything else find out if your mail client can be configured to 
send through them with some sort of authentication so the sending IP 
doesn't matter.
