Its a feature, a frontend running with tcp can use a backend using http.
If you want both to use tcp either put that in the defaults, or specify
it for both frontend&backend.
It seems to me your assumption that the backend automaticaly takes over
the mode from the frontend is wrong. Perhaps a documentation change
could prevent this configuration mistake from being made by others.. To
clarify that setting it in the frontend does not mean it doesnt need to
also be set in the backend.

I think that nails the problem. So if its not just me then the
question is if this is intended behavior or if its a bug. If its
intended then I don't think its entirely clear from the documentation
that 'mode tcp' only works under certain circumstances. If we confirm
that its a bug then I'd be willing to see if I can track it down and
fix it.

Which does not prevent the backend from using mode http as the
defaults section sets.

"mode tcp" is already present in mainfrontend definition below
the bind statement

This one has me stumped - I'm trying to proxy SMTP
connections however I'm getting an HTTP response when I try
to connect to port 25 (even though I've done mode tcp).
This is the smallest subset that reproduced the problem - I
can make this work by doing "mode tcp" in the default
section and then doing "mode http" in all of the http
frontends (not shown). But doing 'mode http' as default and
then 'mode tcp' in the smtp frontend definition seems to not
work and I'm not certain why.
