Anti-spam measures are your enemy.  The reply-to isn't your problem.
Using mailhop outbound, you'll get bitten by SPF: your mailhop won't be
on your ISP's list of allowed servers, and your mail will go into most
domains' bit-bucket.

For twice as much you could use the mailhop inbound to forward to a mail
server in your house (potentially on a high-numbered port), which is
configured to forward everything to your ISP's mail server (in sendmail
parlance, that's the 'smarthost' configuration).  But that requires a
mail server in your house to be up 24x7, which may or may not be a
problem for you.
