问题描述
我有一个Java程序，该Java程序安装在旧的Ubuntu计算机上，并使用javax.mail发送邮件.但是，那台机器崩溃了，我现在在新的CentOS机器上运行相同的Java应用程序.
I have a Java Program that was installed on an old Ubuntu machine and sent mail using javax.mail. However, that machine went down and I am now running the same Java app in a new CentOS machine.
但是，尝试使用mail.smtp.host = 127.0.0.1发送电子邮件时，出现错误"MessagingException:501语法:HELO主机名".
However, I get an error "MessagingException: 501 Syntax: HELO hostname" when trying to send an email using mail.smtp.host = 127.0.0.1.
我的猜测是该CentOS中的邮件服务器尚未激活.
My guess is that the mailserver is not yet activated in this CentOS.
我将如何配置javax.mail可以使用的邮件服务器?
How would I go about configuring a mail server that javax.mail can use?
谢谢
推荐答案
您的计算机主机名必须映射到/etc/hosts文件中.
Your machine host name must be mapped in /etc/hosts file.
示例:控制台显示:linux#然后cat /etc/hostname显示
Example:Console shows: linux#and cat /etc/hostname shows
linux.mydomain.com
然后编辑以root身份运行的主机文件. vi /etc/hosts
Then edit your hosts file running as root . vi /etc/hosts
127.0.0.1 localhost linux linux.mydomain.com
