Hello Sam,
I found that there is declaration of TOFOLDER in filter.html template, but in
code there is no reference to that "variable", i also found reference to
ERRTOFOLDER "variable" in mailfilter.c but it has no declaration in templates.
I think that is one "variable", but was renamed in only one place,
i made patch that rename it in filter.html
