我有这个发送电子邮件的小ejb bean，我在Glassfish上使用JavaMail Session。在Java Mail Session下的Admin Glassfish设置中，我使用Google凭据发送/接收电子邮件。使用Google帐户，我可以接收和发送电子邮件，但是当我尝试使用我的专用服务器的个人电子邮件时，例如my@dommainname.com，那么Glassfish不会发送/接收任何电子邮件。
我怀疑在JavaMail Session下我没有在Glassfish上填写正确的信息。在选项卡＆＃34;高级＆＃34;在JavaMail Session下，有4个字段需要一些关于我的邮件服务器的信息：
Store Protocol: imap
Store Protocol Class:com.sun.mail.imap.IMAPStore
Transport Protocol: smtp
Transport Protocol Class:com.sun.mail.smtp.SMTPTransport
为什么当我使用谷歌Gmail帐户时它完美无缺，但是当我使用自己的域名电子邮件时，它不会发送任何电子邮件或接收？应用程序挂起加载，我收到此错误：
