Question
The ezmlm program was the first to use a technique where this field is modified per individual, called VERP. In one protocol, this field is checked for either “strict” or “relaxed” alignment, after which a user-defined policy specifies one of the actions “none”, “quarantine”, or “reject”. This field is commonly wrapped by adding a hash, timestamp, and the prefix “SRS” in a namesake “Rewriting Scheme”. A “signing domain” specified in the “d=” (“d equals”) tag is consulted over DNS to check that this field is signed correctly in the (*) DKIM (“DEE-kim”) protocol. The DMARC (“DEE-mark”) protocol extends a protocol for verifying this field called SPF, or “[this word] Policy Framework”. This field is also called the reverse path or return path in an SMTP envelope, and is where bounce messages are sent. For 10 points, phishers attempt to forge what field when spoofing an email? ■END■
ANSWER: email sender [accept FROM address; prompt on “email address” with “what field containing the email address?”; accept envelope sender; accept reverse path or return path or return address before mentioned] (Technically, the FROM address and the envelope sender are not exactly the same thing, but I didn’t think it was worth raising the distinction in the question.)
