setEnvelopeFrom cannot find symbol

[Thomas Griffith]

Hello, I receive the following exception...

mail_test.java:88: error: cannot find symbol
message.setEnvelopeFrom(new InternetAddress(username_bounced));
       ^
  symbol:   method setEnvelopeFrom(InternetAddress)
  location: variable message of type Message

with this code. I also tried setSender(..) and receive the same error. Is there anything obvious here, it seems straight-forward and I've been banging my head on this for two days...thank you so much for reading...

import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import javax.mail.internet.InternetAddress;

import javax.mail.Message.*;
import java.lang.Package;


// Create a MimeMessage for sending
Message message = new MimeMessage(session);

String username_bounced="[e-mail]";
String username="[e-mail]";
message.setEnvelopeFrom(new InternetAddress(username_bounced));

message.setFrom(new InternetAddress(username));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[e-mail]));
message.setSubject("Test Subject");

Hi, I also tried casting to SMTPAddress...

((SMTPMessage)message).setEnvelopeFrom(new InternetAddress(username_bounced));

and receive this... it's like something is missing from the javamail jar...

mail_test.java.java:89: error: cannot find symbol
((SMTPMessage)message).setEnvelopeFrom(new InternetAddress(username_bounced));
  ^
  symbol:   class SMTPMessage
  location: class jm6

Maybe I'm looking at the wrong version of the docs, but the one I'm looking at doesn't support a method named "setEnvelopeFrom". Plus, I'm not sure what that's supposed to do for you anyway.

[Norm Radder]

Do you have the import statement for the SMTPMessage class?
My very old doc(2010 javamail-1.4.3) shows:

com.sun.mail.smtp
Class SMTPMessage

java.lang.Object
 extended by javax.mail.Message
     extended by javax.mail.internet.MimeMessage
         extended by com.sun.mail.smtp.SMTPMessage

Hello, Tim, trying to set up a delivery fail bounce back email addy so they are sent there ([e-mail]) rather than [e-mail]... I think setSender is the easier way but I get the same error.

I added this to for the SMTPMessage which apparently has setEnvelopeFrom...

import com.sun.mail.smtp.SMTPMessage;

made the above error chill but now I get

mail_test.java:91: error: incompatible types: InternetAddress cannot be converted to String
((SMTPMessage)message).setEnvelopeFrom(new InternetAddress(username_bounced));

on this line

((SMTPMessage)message).setEnvelopeFrom(new InternetAddress(username_bounced));

[Tim Holloway]

Ooops. Missed the cast. But the argument to setEnvelopeFrom is a simple string, not one of those fancy javamail objects.

[Thomas Griffith]

Tim fixed the error because the arg for setEnvelopeFrom is a string, so it compiles with...

((SMTPMessage)message).setEnvelopeFrom(username_bounced);

not sure it'll run so will be checking that out. I'm not sure why setSender can't work for entering the [e-mail] in the message header, that seems more efficient.

ah, runtime error on the above cast...

java.lang.ClassCastException: javax.mail.internet.MimeMessage cannot be cast to com.sun.mail.smtp.SMTPMessage
        at jm6.main(jm6.java:92)

this is frustrating. ugh. Just trying to send the return address across to handle the bounces.

I had this problem a while back when building a list server and solved it using a creating an instance of Session by passing in properties including mail.smtp.from.  I am just leaving for work so I can't dig into now, but here's the code (more than what you need) that I used to create the Session which supported envelope from.

In the list server's delivery agent, a session was creating with:

	@Inject
	CustomSmtpSessionFactory sessionProvider;
	...
	jakarta.mail.Session session = sessionProvider.getSessionWithCustomizedReturnAddress(envFrom);

import java.util.Optional;
import java.util.Properties;
import java.util.stream.Collectors;

import javax.enterprise.context.Dependent;
import javax.inject.Inject;
import jakarta.mail.Authenticator;
import jakarta.mail.PasswordAuthentication;
import jakarta.mail.Session;

import org.eclipse.microprofile.config.inject.ConfigProperty;
import org.slf4j.Logger; 

@Dependent
public class CustomSmtpSessionFactory {
	@ConfigProperty(name = "distlist.smtp.host")
	String host;

	@ConfigProperty(name = "distlist.smtp.port")
	String port;

	@ConfigProperty(name = "distlist.smtp.transportProtocol")
	String transportProtocol;

	@ConfigProperty(name = "distlist.smtp.auth")
	String useAuth;

	@ConfigProperty(name = "distlist.smtp.username")
	Optional<String> username;

	@ConfigProperty(name = "distlist.smtp.password")
	Optional<String> password;

	@ConfigProperty(name = "distlist.smtp.starttlsEnable")
	String starttlsEnable;

	@ConfigProperty(name = "distlist.smtp.from")
	String from;

	@ConfigProperty(name = "distlist.smtp.useSsl")
	boolean useSsl;

	@ConfigProperty(name = "distlist.smtp.bypassCertificateTrust")
	boolean bypassCertificateTrust;

	@Inject
	Logger logger;

	public Session getSession() {
		return getSessionWithCustomizedReturnAddress(from);
	}

	public Session getSessionWithCustomizedReturnAddress(String envFrom) {
		Authenticator auth = new jakarta.mail.Authenticator() {
			protected PasswordAuthentication getPasswordAuthentication() {
				String authUsername = username.orElse("");
				String authPassword = password.orElse("");
				logger.debug("getSessionWithCustomizedReturnAddress: auth-username={} auth-password={}", authUsername,
						authPassword);
				return new PasswordAuthentication(authUsername, authPassword);
			}
		};

		Properties props = new Properties();
		props.setProperty("mail.smtp.host", host);
		props.setProperty("mail.smtp.port", port);
		props.setProperty("mail.transport.protocol", transportProtocol);
		props.setProperty("mail.smtp.socketFactory.fallback", "true");
		props.setProperty("mail.smtp.socketFactory.port", port);
		props.setProperty("mail.smtp.auth", useAuth);
		props.setProperty("mail.smtp.starttls.enable", starttlsEnable);
		props.setProperty("mail.smtp.from", envFrom);

		if (useSsl) {
			props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
		}
		if (bypassCertificateTrust) {
			props.setProperty("mail.smtp.ssl.trust", "*");
		}

		String propDetails = props.entrySet().stream().map(entry -> entry.getKey() + "=" + entry.getValue())
				.collect(Collectors.joining(",  "));
		logger.debug("getSessionWithCustomizedReturnAddress: properties={}", propDetails);

		return Session.getInstance(props, auth);
	}
}

Just an observation. Doubtless you've seen emails from "orders.amazon.com" saying your credit card has just been billed $779 and call this number to cancel. But if you actually expand the headers, you'll see that the "sent from" address is "scuzzbag.info" or something like that.

One is the claimed sender ID, but the other is the actual ID that the sending mailserver required its client to connect as. So that should explain the difference.

thank you, Ron and Tim. Would these two lines overwrite the other?...the session Property and the message.setRecipients...

props.setProperty("mail.smtp.from", username_bounced);
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(original_recipient));

I'm confused there. One says "from", the other says "recipients" (to). So no apparent conflict. Although here again, the recipients should be one or more Strings, I believe.
