# SMTP sink-MX for the e2e stand (plan C.4): accepts any mail on 25 and dumps
|
|
# each transaction to its own file under /mail, so the test harness can read
|
|
# the raw received message (headers + body, including the DKIM-Signature
|
|
# Postfix/OpenDKIM added) straight off disk. smtp-sink ships in the postfix
|
|
# package itself — no new dependency.
