sorry german


with listescape plugin enabled something like

require
["reject","variables","date","fileinto","mailbox","envelope","subaddress","regex","copy","include"];
# Extract date info
if currentdate :matches "year" "*" { set "year" "${1}"; }
if currentdate :matches "month" "*" { set "month" "${1}"; }
if currentdate :matches "day" "*" { set "day" "${1}"; }
if envelope :detail :matches "to" "*" { set :lower "to" "${1}"; }
if true {
if header :contains "Return-Path" "${to}@domain.de" { fileinto :create
"user-backup/${year}/${month}/${day}/${to}/out";}
else { fileinto :create "user-backup/${year}/${month}/${day}/${to}/in";}
stop;
}
