work is already done imho, dont know how much hard work is left or if its stable to use, but i try to find what will be really cool to have in android with aquamail
Using roundcube webmail here that can edit sieve filters, this then also works for aquamail, if the sieve editor is added it would imho be 100% perfect as is
