No, currently not.

BTW: "if two copies of a message with the same message-id and the same 
envelope receipient are received."
I know that MessageIDs are supposed to be globally unique, but one cannot 
count on it.

This feature had been asked several times; it should be possible to code 
using the "extdata" plugin API in newest Sieve, see the last messages in 
the list.
