I get the following exception when trying to send a mail with JavaMail with OAuth2:...

I found the solution myself. Maybe somone can make use of it:
The code above was not false to my knowledge. The actual reason was, that I should not have used a token acquisition with client credentials but only with username/password and client id.
I am not sure if JavaMail supports this because in the documentation I could not find anything about it. The rare examples about this are usually with client credentials.
As you can see above, no AUTH command was triggered because I had not the permission to do it obviously.
What I needed to do aswell was to use the Microsoft Graph API not only to aquire a token via "password/username provider" (this type) instead of the "client credential provider" (link) but also to actually trigger a send mail command via Microsoft Graph API (link).
The client credential provider was in my case not sufficient because the admin had not specified permissions to send mails.
Thus, I didn't use JavaMail anymore for this and needed another token acquisition provider.

I have an angular app(contact form) and springboot app which i am using for sending email through gmail when the contact form is submitted.
The issue i am experiencing is that the negative case is not getting captured, in the sense, if my springboot app(email) is down, my angular app still says its success instead of saying "email service is down". Currently what is happening is, in both cases status success is sent, even if the springboot app is down.
Somewhere my condition is not working, any kind of assistance will be really helpful.

My springboot App is working fine in DEV environment, and now i would like to segregate DEV and PROD environments in order for it to pickup respective code.

I have a system where (registered) users have the possibility to add their own SMTP server for mail sending. Thus I don't know in advance what server a user might add and whether this one supports SMTPUTF8. Now starting from JavaMail 1.6 support for SMTPUTF8 has been added. After enabling this for some servers the following line is printed to the log:
mail.mime.allowutf8 set but server doesn't advertise SMTPUTF8 support
This is correct for that server, however how can I detect whether a server supports this or not? I see two possibilities:
- Somehow detect whether a mail server supports SMTPUTF8 - if that is possible?
- Add another parameter to the stmp configuration and then the users decide (which in most cases they don't really know I would guess)
So is there a way to detect whether a server supports SMTPUTF8?
I checked the implementation and the com.sun.mail.SMTPTransport seems to provide such a query possibility.

Using ESMTP with the EHLO command one can query the smtp server for supported extensions.
mail.smtp.ehlo=true; must be enabled.

Thank you to all those who replied.
It appears that all the problem was cause by a change on Microsoft policies regarding the basic authentication for their tenants.
After some changes on the account settings, all is back to normal and the emails are sent again.
Since JavaMail version 1.6.0 classes Store and Folder (amongst Transport) should implement AutoClosable interface.
I did not find any examples of someone using JavaMail API with auto-closable.
After a few tests I am not sure how to exactly use this feature as I have discovered a strange(?) behavior.

Try to restructure the code as:
No vulnerabilities reported
You can use javamail like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the javamail component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
