-"""mailu — recipe-specific functional test #2 (Phase 2 P3, the characteristic end-to-end mail flow).
-
-Provision a mailbox, INJECT a uniquely-marked message to it via the postfix container's local
-`sendmail` (locally-originated → not greylisted, no auth/TLS needed), then VERIFY it was DELIVERED
-and STORED by polling dovecot's `doveadm search` in the imap container. This is mailu's defining
-behaviour (it is a mail server): a real postfix → rspamd → dovecot deliver→store→fetch round-trip,
-not an API/health stand-in.
-
-We use the in-container mail tools (sendmail/doveadm) rather than the host network ports because the
-TLS_FLAVOR=notls deploy makes dovecot refuse plaintext auth over the network (143) — the in-container
-path exercises the same delivery/storage stack without that constraint, and avoids rspamd greylisting
-of network senders.
