Customer servers, plural? That could be a problem. How would you

This does nothing because packets can never arrive from the outside
with a destination IP of 10....

Yes. Since you are using a 2.0.xx kernel, you would need to apply
the port forwarding kernel patch and then use ipportfw to set up
forwarding for the SMTP port to a *single* 10.... address.
But if you want to route mail to multiple masqed servers, this won't
do the job. I'd suggest setting up sendmail on the Linux box to
relay for all your customer domains. Then masquerading would not be
involved.
