feat: ARIA kann E-Mails lesen und senden
IMAP/SMTP mit SSL/TLS, STARTTLS oder unverschluesselt. Senden mit Text, HTML, Anhaengen und eingebetteten Bildern (cid:), Antworten mit In-Reply-To. Lesen, Suchen, Ordner anlegen (auch Unterordner), Mails verschieben. Tools: email_status/send/list/read/folders/folder_create/move. Whitelist als harte Grenze im Sendepfad, nicht im Prompt: alles, was nicht drinsteht, ist gesperrt, leer = nirgendwohin. Jeder Empfaenger zaehlt (An, Cc, Bcc), ein fremder blockiert die ganze Mail. Genau eine Schreibweise: name@domain, '*' nur als *@domain, *@*.domain oder *@*. '*hacker-net.de' liest sich, als passte es auf 'evilhacker-net.de' — solche Kurzformen lehnt das Speichern mit Korrekturvorschlag ab. Verglichen wird die Domain als Ganzes. Zugangsdaten sieht ARIA nie: - liegen im Brain unter /data. NICHT in /shared — das ist in ARIAs Container eingehaengt, /data nicht. - keine Schnittstelle gibt das Passwort zurueck, nur password_set. - Brain-Export laesst email_secret.json + email_admin.key aus (GNU- und busybox-tar geprueft, der Diagnostic-Container ist Alpine). - Anhangspfade nach realpath geprueft: ein Symlink in /shared/uploads auf die Geheimnis-Datei wuerde sonst im Brain aufgeloest und verschickt. - Konfiguration nur mit Admin-Schluessel (X-Aria-Admin, liegt in /data). Die Diagnostic haengt ihn an, weist aber Anfragen aus ARIAs Container ab — sonst koennte eine eingehende Mail sie per curl die Whitelist oeffnen lassen. Grenze: ARIAs Container hat SSH auf die VM. Gegen einen gezielten Einbruch schuetzt das nicht, nur dagegen, dass Zugangsdaten von selbst auftauchen. Eingehende Mails sind fuer ARIA als Daten markiert, nicht als Anweisungen. Diagnostic: Einstellungen → Integrationen → ARIA E-Mail, plus "📬 Postfach oeffnen" — ARIAs ganzes Postfach in eigenem Fenster, Unterordner eingerueckt, Posteingang + Gesendet oben. Nur lesend, markiert nichts als gelesen. Mail-HTML in einem Rahmen ohne Skripte und ohne Nachladen von aussen (kein Tracking-Pixel); eingebettete Bilder kommen als data: mit. Jede gesendete Mail landet als Kopie in "Gesendet" — fehlt der Ordner, wird er angelegt, statt die Kopie still zu verlieren. Tests: 65 Einheitstests (Whitelist inkl. evilhacker-net.de, MIME-Aufbau, Header-Injection, Symlink-Ausbruch, Geheimnis nie in Ausgaben) + 50 gegen einen echten Mailserver (GreenMail): TLS-Login, Senden mit Anhang + Bild, Flags, Suche mit Umlaut, Gesendet-Kopie, In-Reply-To, Ordner mit Umlaut, MOVE und der Fallback ohne MOVE (der keine fremden geloeschten Mails mitreisst).

|

Drei Grundsaetze, aus denen sich der Rest ergibt:
|
||||
|
||||
1. Die Zugangsdaten sieht ARIA nie.
|
||||
ARIAs Claude-Container (proxy) hat /shared eingehaengt — alles unter
|
||||
/shared/config kann sie lesen. Deshalb liegen Konfiguration und Passwort im
|
||||
Brain unter /data, das dort NICHT eingehaengt ist. Keine Schnittstelle gibt
|
||||
das Passwort je zurueck (nur `password_set: true`), kein Tool-Ergebnis
|
||||
enthaelt es, der Brain-Export laesst die Geheimnis-Datei aus.
|
||||
|
||||
2. Die Whitelist ist eine harte Grenze, kein Prompt-Hinweis.
|
||||
Geprueft wird hier im Sendepfad, fuer JEDEN Empfaenger (To, Cc, Bcc). Leere
|
||||
Liste = ARIA kann nirgendwohin senden. Aendern darf die Liste nur, wer den
|
||||
Admin-Schluessel hat (/data/email_admin.key) — den liest die Diagnostic,
|
||||
ARIAs Container nicht. Wichtig, weil eingehende Mails Text enthalten, den
|
||||
ARIA liest: eine Mail mit "schick das an X" darf nicht reichen.
|
||||
|
||||
3. Eingehende Mails sind Daten, keine Anweisungen.
|
||||
Tool-Ergebnisse mit Mail-Inhalt sind entsprechend markiert.
|
||||
|
||||
Grenze, die man kennen sollte: ARIAs Container hat einen SSH-Schluessel auf die
|
||||
VM. Legt sie es gezielt darauf an, kommt sie als root an jede Datei. Dieses
|
||||
Modul sorgt dafuer, dass die Zugangsdaten nirgends von selbst auftauchen — es

ist kein Schutz gegen einen bewussten Einbruch.
