Hallo,

ich versuche verzweifelt eine IMAP bzw. SMTP Konfiguration zu konfigurieren.
Benutzer sollen über beliebige Mailclients von extern per IMAP/SMTP Mails empfangen und versende können.
Die IMAP-Verbindung scheint zu funktionieren - bei der authentifizierten SMTP-Verbindung (kein anonymes Relay) komme ich nicht weiter.

Ich bekomme folgende Meldung:
530 5.7.57 SMTP; Client was not authenticated to send anonymous mail during MAIL FROM,

Zertifikat wurde bereits eingerichtet.
Anbei der entsprechende log-Auszug.
Weiter unten Screenshots von meiner Empfangsconnector-Konfiguration und meinen Sendeversuchen.

Hat jemand eine Idee wo das Problem liegt? Googeln hat mir bis jetzt noch nicht geholfen.

Servus,

hast du die Konfiguration einmal geprüft wie es Paul hier beschrieben hat?

Hast du das schon lösen können, oder ist es noch ein Problem?

Hallo zusammen,

 

ich habe gerade das gleiche Problem gelöst. Vermutlich ist der Empfangsconnector vom Typ "Frontendtransport"?
Damit "proxiet" er der nur - an den "Client Proxy <Servername>". Beide müssen korrekt konfiguriert sein:

Get-ReceiveConnector "<dein_SMTP_Empfangsconnector>" | Add-ADPermission -User "NT-AUTORITÄT\Authentifizierte Benutzer" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Sender"
Get-ReceiveConnector -Identity "Client Proxy <dein Servername>" | Add-ADPermission -User "NT-AUTORITÄT\Authentifizierte Benutzer" -ExtendedRights ms-exch-smtp-accept-authoritative-domain-sender

Bei mir fehlte in dem Client Proxy die "ms-exch-smtp-accept-authoritative-domain-sender" Berechtigung.

Ob du die ms-Exch-SMTP-Accept-Any-Sender brauchst, musst du schauen - ich habe ein Konto benötigt, das in einer Software hinterlegt wird, die für verschiedene User Mails versendet.

Muss man auch erst einmal finden....

Grüße

Sebastian
