SMTP relay und hmailserver werden leider geblockt/gefiltert

MrBac

Hallo Forum,

ich habe ein größeres Problem, aber zuerst meine Technik.

Ich habe einen Server der hostet mehrere VM's (darunter die Sophos UTM) dieser Server holt per Hmailserver von meinem Provider die Emails ab und sollte diese per SMTPRelay der sophos utm an meinen Mailserver weiterleiten (die UTM wird hauptsächlich als Spamfilter und Emailschutz verwendet).

Das funktioniert auch in der Regel mit manchen Accounts, aber nicht mit allen. Ich habe jetzt mal Gesniffed und gesehen das die UTM ein 503 an meinen Hmailserver weiterleitet. Woran könnte das an der UTM liegen?

Gibt es eine Einstellung die ich übersehen habe?

Grüße

Michael

    Hallo Michael,

    (Sorry, my German-speaking brain isn't creating thoughts at the moment. Frowning2)

    Please copy here lines from the SMTP Proxy log for an email successfully received from an account and also lines for an unsuccessful one.

    The only lines in SMTP logs with "503" I've seen were ones with size="503".  Is that what you mean, or is that a 503 from the Web Filtering log?

    MfG - Bob (Bitte auf Deutsch weiterhin.)
