If you've got a static IP (or an acceptably predictable and narrow 
range) where the smarthost can expect you to connect from, no patch is 
required. See "How do I set up a null client?" at 
https://cr.yp.to/qmail/faq/outgoing.html#null-client (and the format of 
control/smtproutes is described further in qmail-remote(8)).

If your smarthost needs you to authenticate, you'll need a patch. I 
haven't used one myself, but https://www.fehcom.de/qmail/smtpauth.html 
is what I'd try first. Maybe someone with practical experience can weigh 
in on what they've used.
