That is strange. This could mean that the envelope is passed a bit 
differently than you think. Those headers are only used by Dovecot if no 
other sources are available for envelope information.

Do you see anything strange in the logs?

You could try the following Sieve script to get a bit more information 
(perhaps I should make a normal debug log line for this).

require "vnd.dovecot.debug";
require "envelope";
require "variables";

# Get envelope
if envelope :matches "to" "*" { set "env_to" "${1}";  }

debug_log "ENVELOPE_TO: ${env_to}";

You need to enable the vnd.dovecot.debug extension in your 
sieve_extensions= setting.

The debug line will be logged in the user log (e.g. ~/.dovecot.sieve.log)
