javax.mail.MessagingException：[EOF]

Question

我在使用smtp.gmail.com或smtp-relay.gmail.com通过SMTP发送通知时遇到问题。这是给出的错误

注意：我使用Oracle Weblogic Server进行SMTP通知。

<BEA-320047> <Mail notification has not been sent due to an error that occurred while creating or sending a mail message:

我对如何解决这个问题一无所知，周五截止日期确实有一个截止日期:(非常需要这方面的帮助。先谢谢你们。
