FWIW, I don't think this is possible without doing odd things to your
routing, and it probably wouldn't make much sense anyway.  Otherwise,
I believe sendmail would receive connections on eth1, and then reply
out of... which interface?  The process which initiated the connection
would likely receive responses from a different IP than it was
connected to (if at all, depending on the routing), and quite possibly
ignore them.  I suspect this is the problem you're already having,
only in reverse.
