OK, then I am not sure it is possible. Some providers support limited SIEVE
features, but the only ones I have seen support it only though editing rules via
a web interface that only allows a very small subset of what sieve can do.
Without coordinating with those providers, it's unlikely you will be able to
get anything to work.
Isn't the whole point of sieve that it is server-side filtering and rules?
So you need to be able to write the sieve files to the appropriate location
which, unless someone is truly mad, is going to be outside the IMAP store where
a client cannot simply write a sieve file.
