我正在尝试使用 Play Framework 发送电子邮件。在 applications.conf 中,当我设置 smtp.mock=true 时,它运行良好:
[info] application - HTML: Welcome to Play20StartApp. <br> Click on this link : http://localhost:9000/confirm/d77ea256-0d2e-4df5-b66e-e034159f8042 to confirm your email.<br><br>--<br>null
[debug] application - Mail sent - SMTP:smtp.google.com:465 SSL:yes user:username@gmail.com password:password
但是,当我评论 smtp.mock=true 并尝试发送真实电子邮件时,我收到此错误:
[debug] application - Mail.sendMail: Mail will be sent to user1@gmail.com
[ERROR] [09/26/2013 03:46:05.014] [application-akka.actor.default-dispatcher-2] [TaskInvocation] From address required
org.apache.commons.mail.EmailException: From address required
我已将 smtp.user 设置为适当的值,即 server@businessdomain.com 。知道是什么导致了这个错误吗?
故障排除步骤
- 使用的电子邮件是真实的电子邮件,出于发布的目的,它们是匿名的。同样,使用真实域名
- 使用工作的本地邮件服务器 (exim) 进行测试,以及通过 Gmail (smtp.google.com) 和 Google Apps (aspmx.l.google.com) 服务器直接发送。这些设置已使用邮件客户端进行了验证。
下面的 Java 代码片段完美运行,
导入 java.util。; 导入 javax.mail。; 导入 javax.mail.internet。; 导入 javax.activation。;
public class SendEmail { public static void main(String [] args) { String to = "recipient@mydomain.com"; String from = "sender@mydomain.com"; String host = "localhost"; Properties properties = System.getProperties(); // Setup mail server properties.setProperty("mail.smtp.host", host); // Get the default Session object. Session session = Session.getDefaultInstance(properties); try{ MimeMessage message = new MimeMessage(session); // Set From: header field of the header. message.setFrom(new InternetAddress(from)); message.addRecipient(Message.RecipientType.TO, new InternetAddress(to)); message.setSubject("Subject of email"); message.setText("This is actual message"); Transport.send(message); System.out.println("Sent message successfully...."); }catch (MessagingException mex) { mex.printStackTrace(); } } }
