Spring Mail working but sudden "Got bad greeting from SMTP host"

This past week, my email service project has been working completely fine, but today when I try to run it in Eclipse it throws a:
org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Got bad greeting from SMTP host: mail.test.com, port: 25, response: 554 mail.test.com
. Failed messages: javax.mail.MessagingException: Got bad greeting from SMTP host: mail.test.com, port: 25, response: 554 mail.test.com
What could be the sudden cause of this? Now, my SpringBoot main class won't end, I have to manually terminate it.

SMTP error 554 is kind of generic.
It usually means the remote host has decided it will not accept the message you are attempting to send (maybe because your sending server is blacklisted), and the rejection is permanent.
You need to talk to the admin on the receiving server (mail.test.com) to find out why your message is being rejected.

The error message also points to an SSL connection. Seems like you are trying to connect to an SSL port using standard SMTP TCP. Here is a Stack Over flow that has a similar error message.
unrecognized ssl message plaintext connection exception

Make sure you use correct SSL port number. By default SSL/TLS encrypted SMTP uses port 465.

javax.mail.MessagingException: Could not connect to SMTP host: smtp.live.com, port: 587

I've implemented a code that sends e-mails using Outlook server (worked fine locally).
What's the cause of the following exception on my production environment and how do I resolve it?
javax.mail.MessagingException: Could not connect to SMTP host: smtp.live.com, port: 587; nested exception is: java.net.ConnectException: Connection timed out

Java Mail Error : java.net.ConnectException: Connection refused: connect

I am stuck with the mail sending with Java Mail API.
I am not able to connect SMTP server with any kind of properties... I have tried with different combination.
I am connecting SMTP Remote server (Server is not at localhost, its in LAN), with port 25 but it gives me the port error to 465, I dont know why ?
javax.mail.MessagingException: Could not connect to SMTP host: *RemoteIP*, port: 465; nested exception is: java.net.ConnectException: Connection refused: connect
If anyone can help.
Thankx in advance.

Maybe your mail server is actually using SMTPS on port 465 (although it's not the recommended port). If that is the case you can see here an example of using JavaMail with SMTPS. Note the property mail.smtps.host; you also have the mail.smtps.port property to specify 465.
