There are so many damned options within just the "get mail" area, that
it's easy to not get what you want. I'll e-mail you my sample
"daily.spf". This may give you an idea if you're doing things right
and the software is buggering you, or if you've missed a scripting
feature.
BTE, the software is pre-release Beta, but there will be documentation
when it is officially released.
