E-Mail-Parameter mail.transport.protocol fehlt bei zusätzlichem Mandanten

Zusammenfassung

Zusätzlichen Mandanten fehlt der E-Mail-Parameter mail.transport.protocol, weshalb keine E-Mails verschickt werden können.

Schritte zum Reproduzieren

  1. Hauptmandant anlegen
  2. E-Mails korrekt konfigurieren, Versand ist möglich
  3. zweiten Mandant anlegen
  4. System/Parameter/E-Mail ist jetzt teilweise vorbelegt, aber nicht vollständig. In diesem Tab die fehlenden Werte eintragen.
  5. Über System/Parameter/E-Mail-Admin eine Test-Email verschicken

Aufgefallen ist das Problem bei Release 1.1.6, was aus einer Migration von einem ursprünglichen 1.0.11 hervorging. In den Commits habe ich aber auf Anhieb keine Änderungen gesehen, die an diesem Verhalten etwas ändern sollten.

Modul, Maske, Terminal, API-Aufruf, Bericht

Am besten sichtbar ist der Fehler im Test-Email-Versand in System/Parameter/E-Mail-Admin. Tatsächlich werden aber auch keine anderen E-Mails verschickt.

Wie ist das aktuelle Fehlerverhalten?

Es werden keine E-Mails verschickt. Der Client zeigt an:

Es ist ein unerwarteter Fehler aufgetreten:

Was ist das erwartete richtige Verhalten?

Es werden E-Mails verschickt. Der Client zeigt an:

Das Log stammt aus Release 1.1.6, wo die entsprechenden Code-Zeilen lauten:

public void send(String smtpHost, String user, String password, Message message) throws javax.mail.MessagingException {
		if (ServerConfiguration.getIsDevEnvironment()) {
			myLogger.info("LPMail send() -> " + message.toString());
			return;
		}

		String transportProtocol = mailSession.getProperties().getProperty("mail.transport.protocol");
		if (transportProtocol.equalsIgnoreCase("graph")) {
			sendGraphService(message, clientSecretCredential(mailSession.getProperties()) );
		} else {
			Transport transport = mailSession.getTransport("smtp");
			transport.connect(smtpHost, user, password);
			transport.sendMessage(message, message.getAllRecipients());
			transport.close();
		}
	}

Mögliche Korrekturen

Per Hand in System/Parameter/E-Mail den Parameter "mail.transport.protocol" auf "smtp" setzen.
