Section 5.4 says:
Unless explicitly overridden with a :from parameter, the From field SHOULD be set to the address of the owner of the Sieve script.
It should say:
Unless explicitly overridden with a :from parameter, the From field SHOULD be set to the address of the owner of the Sieve script. Informative advice: Users often have multiple email addresses, and "the address of the owner of the Sieve script" may offer a choice among several. If the sieve processor recognizes an address belonging to the owner of the Sieve script in the To or Cc fields of the input message, then it's better to use that address for the From field of the generated message, rather than any other addresses the script's owner may also have.
The added text represents the intent of the working group for selecting "the address of the owner" in cases where the owner has multiple addresses known to the Sieve engine. Normative text would not be appropriate here, but an informative note clarifies the WG's intent.
