about

nx_email_mta_gate.nx -- GATE for EMAIL R7 (receiving MTA, nx_email_mta). The INTEGRATION CAPSTONE: a full inbound SMTP session composed across rungs -- R7 command parse + policy + FSM, R4 (nx_pop3_dedot) to unstuff the DATA stream, R3 (nx_email_mailbox over nx_seg_store) to DELIVER, then fetch the stored message back BYTE-IDENTICAL = receive->store proven end to end. COMPLETENESS : EHLO/MAIL/RCPT/DATA/QUIT classified + correct reply codes (250/250/250/354/221); DATA dot-unstuffed; delivered + fetched byte-exact. POLICY/SEC : RCPT for our domain accepted; RCPT to a foreign domain REFUSED with 550 (open-relay defense). NEG-CONTROL : a command out of sequence (RCPT before MAIL) -> 503. Evidence -> knowledge/status/email_mta.log (MTAGATE ... verdict=GREEN) license_tier: ORIGINAL
