An alternative to the solution with tables is a vararg function:
function is_one_of(value, ...)
for k, v in ipairs(arg) do
if v == value then return true end
end
end
You can use it like this:
if is_one_of(strCustomPropertyValue,
"inbox", "thisweek", "thismonth", "thisyear", "later",
"someday", "archive", "otherpersons") then
...
end
