I'd recommend my own getmail over fetchmail; however, if you want to use
fetchmail, configure it to use an MDA rather than delivering by
re-injecting with SMTP. Postmasters all over the net will thank you for
it.

Use a catchall virtual domain and maildirsmtp. In your link-up script,
call maildirsmtp to deliver all the mail to your ISP's smarthost. You
can deliver directly, but maildirsmtp isn't meant for this; you'd have
to do a lot more fiddling.

If the local domain is in locals or virtualdomains (as it should be),
this is automatic.
