Mail Server with javax.mail and CentOS

由 走远了吗. 提交于 2020-01-14 09:19:33
问题 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. However, I get an error "MessagingException: 501 Syntax: HELO hostname" when trying to send an email using mail.smtp.host = 127.0.0.1. My guess is that the mailserver is not yet activated in this CentOS. How would I go about configuring a mail server that javax.mail can use? Thank you 回答1: Your machine

问题 Below is one of the targets that runs after the completion of tests, buil.xml(pass or fail). This target is failing and giving error "java.lang.ClassNotFoundException: javax.mail.internet.MimeMessage". So I expanded the mail.1.4.jar file and saw this class was there.

Now I am not able to understand why I am

问题 I use javax.mail.internet.MimeBody* version 1.4.1 My program wants to send some binary data with multiple level of nesting from a server to client using MimeMultiPart.
