Send email with html Java - java

I'm sending email with HTML code inside and everything fine except some bug with charset I think.
My Java code:
public static void sendMail(String to, String from, String body, String subject) {
Properties properties = System.getProperties();
properties.setProperty("mail.smtp.host", "smtp.gmail.com");
properties.setProperty("mail.smtp.socketFactory.port", "465");
properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
properties.setProperty("mail.smtp.auth", "true");
properties.setProperty("mail.smtp.port", "465");
Session session = Session.getDefaultInstance(properties, new Authenticator() {
#Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(GMAIL_USERNAME, GMAIL_PASSWORD);
}
});
try {
MimeMessage message = new MimeMessage(session); // email message
message.setFrom(new InternetAddress(from)); // setting header fields
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
message.setSubject(subject); // subject line
message.setContent(body, "text/html");
message.setHeader("charset", "UTF-8");
Transport.send(message);
} catch (MessagingException mex) {
mex.printStackTrace();
}
My html content:
String htmlCode =
"<h2>ZDelivery<h2>"+
"<br/><button><a href='"+confirmString+"'>Активировать аккаунт</a></button>";
And email which I got:
What I've missed?

The encoding is transferred by the email header field Content-Type, which is set by the mime type argument of the setContent() method:
message.setContent(body, "text/html; charset=UTF-8");
By not setting the charset in the mime type, java will set it for text/html to ISO-8859-1 (which is the default value defined in RFC-2854).
Your are setting the email header field charset. This is not a officially email header field and thats why it is ignored by the email client.

How to put Image in mail's header(Spring Boot)?

I am developing an app where I need to set image in a header and footer of a mail. I saw method setHeader(String header-name, String header_value) but when I put into it a path to my image I don't get anything.
This is my code:
public static void send(String host, String port,
final String userName, final String password, String toAddress,
String subject, String htmlBody,
Map<String, String> mapInlineImages)
throws AddressException, MessagingException {
// sets SMTP server properties
Properties properties = new Properties();
properties.put("mail.smtp.host", host);
properties.put("mail.smtp.port", port);
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.starttls.enable", "true");
properties.put("mail.user", userName);
properties.put("mail.password", password);
// creates a new session with an authenticator
Authenticator auth = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password);
}
};
Session session = Session.getInstance(properties, auth);
// creates a new e-mail message
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(userName));
InternetAddress[] toAddresses = { new InternetAddress(toAddress) };
msg.setRecipients(Message.RecipientType.TO, toAddresses);
msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setHeader("image1", "D:\\broki\\src\\main\\resources\\imageHeader.jpg");
// creates message part
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(htmlBody, "text/html");
// creates multi-part
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
// adds inline image attachments
if (mapInlineImages != null && mapInlineImages.size() > 0) {
Set<String> setImageID = mapInlineImages.keySet();
for (String contentId : setImageID) {
MimeBodyPart imagePart = new MimeBodyPart();
imagePart.setHeader("Content-ID", "<" + contentId + ">");
imagePart.setDisposition(MimeBodyPart.INLINE);
String imageFilePath = mapInlineImages.get(contentId);
try {
imagePart.attachFile(imageFilePath);
} catch (IOException ex) {
ex.printStackTrace();
}
multipart.addBodyPart(imagePart);
}
}
msg.setContent(multipart);
Transport.send(msg);
}
}
As you can see in part
msg.setHeader("image1", "D:\\broki\\src\\main\\resources\\imageHeader.jpg")
I put some key and value which is path to my Image which I want to set into header. But nothing happens. Can someone help me?
The word "header" in a MIME message refers to a section of the message that has "key: value" fields. This section is called "header" because it's transmitted before the "body" content of the message. The headers are for things like "Date", "Subject", "Content-Type".
The word "header" does not refer to a graphical header that would be visible on the screen or when printed. To add this type of a header, you have to modify the content of the message. In your program, that's stored in the htmlBody variable.
I don't think you can simply modify htmlBody to add a header to it, without knowing how it is structured. In the general case, the page header has to be incorporated in the HTML message design from the start.

Session in JavaMail

In the following Code in the session object (PasswordAuthentication ) what username and password we have to provide to send mail ? Sender's username password or receiver's credentials?
I am really confused , I am using java Mail to send mail
public void sendMail(String email,String token)
{
// Recipient's email ID needs to be mentioned.
String to = email;
// Sender's email ID needs to be mentioned
// Assuming you are sending email through relay.jangosmtp.net
String host = "smtp.gmail.com";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.port", "587");
// Get the Session object.
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
// Create a default MimeMessage object.
Message message = new MimeMessage(session);
// Set From: header field of the header.
message.setFrom(new InternetAddress("Issme-Customer-Service"));
// Set To: header field of the header.
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to));
message.setSubject("Email Verification Of issme Account");
message.setContent(
"<h2>Email Verification </h2>" +
"<h3> Please goto the following URL to verify your ISSME account\n </h3> " +
token , "text/html; charset=utf-8");
// Send message
Transport.send(message);
System.out.println("Sent message successfully....");
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
You need to send the sender's credentials which gmail's SMTP server will authenticate and then it'll send the email.

Have you tried something like :
MimeMessage message = new MimeMessage(sesion);
.
.
.
//Config your message....
Multipart mp = new MimeMultipart();
MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent("RTF HTML TEXT", "text/html");
mp.addBodyPart(htmlPart);
message.setContent(mp);
Transport.send(message);

Just check if you have enabled logging in from "Less Secure Apps" using this link. This setting needs to be enabled for the account from#gmail.com.

Setting the "from" header field in Java MimeMessage not working correctly

For a web application I'm working on I made a method to send email notifications. The message has to come from a specific account, but I would like the "from" header field to read as an entirely different email address. Here is my code (I've changed the actual email addresses to fake ones):
public static boolean sendEmail(List<String> recipients, String subject, String content){
String header = "This is an automated message:<br />"+"<br />";
String footer = "<br /><br />unsubscribe link here";
content = header + content + footer;
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
//This is where the email account name and password are set and can be changed
return new PasswordAuthentication("ACTUAL.ADRESS#gmail.com", "PASSWORD");
}
});
try{
MimeMessage message = new MimeMessage(session);
try {
message.setFrom(new InternetAddress("FAKE.ADDRESS#gmail.com", "FAKE NAME"));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
message.setReplyTo(new Address[]{new InternetAddress("no-reply#gmail.com")});
for(String recipient: recipients){
message.addRecipient(Message.RecipientType.BCC,new InternetAddress(recipient));
}
message.setSubject(subject);
message.setContent(content,"text/html");
Transport.send(message);
return true;
}catch (MessagingException mex) {
mex.printStackTrace();
return false;
}
}
For the above method sending an email with it will have the following email header:
from: FAKE NAME <ACTUAL.ADRESS#gmail.com>
I want it to read:
from: FAKE NAME <FAKE.ADRESS#gmail.com>
What am I doing wrong? Any help is appreciated!
What you are looking to do is called "spoofing." It appears as though you are using Google's SMTP servers, if this is the case, you will not be able to do this successfully. For security purposes, Google will only allow the "from" address to be the authenticated email address.
