The email gets sents only to the last email address in the String[] to array. I'm intending to send to all email addresses added to the array. How can I make that work?
public void sendMail(String from, String[] to, String subject, String msg, List attachments) throws MessagingException { // Creating message sender.setHost("smtp.gmail.com"); MimeMessage mimeMsg = sender.createMimeMessage(); MimeMessageHelper helper = new MimeMessageHelper(mimeMsg, true); Properties props = new Properties(); props.put("mail.smtp.starttls.enable", "true"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.port", "425"); Session session = Session.getDefaultInstance(props, null); helper.setFrom(from); helper.setTo(to); helper.setSubject(subject); helper.setText(msg + "<html><body><h1>hi welcome</h1><body></html", true); Iterator it = attachments.iterator(); while (it.hasNext()) { FileSystemResource file = new FileSystemResource(new File((String) it.next())); helper.addAttachment(file.getFilename(), file); } // Sending message sender.send(mimeMsg); }

Sending Email to Multiple RecipientsFor adding Email in 'TO' field, you may use Message.RecipientType.To . Similarly for adding Email in 'CC' and 'BCC' fields, you will have to use Message.RecipientType.CC and Message. RecipientType. BCC.
In short, to send to multiple recipients you should set the header to be a string of comma delimited email addresses. The sendmail() parameter to_addrs however should be a list of email addresses.
You have the choice to use the following 4 methods. I have provided examples of the two methods useful in this case. I have consolidated this information from the commentators below.
helper.setTo(InternetAddress.parse("[email protected],[email protected]")) helper.setTo(new String[]{"[email protected]", "[email protected]"});

The better approach is to create an array containing the address of multiple recipients.
MimeMessageHelper helper = new MimeMessageHelper( message, true ); helper.setTo( String[] to ); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
