'Is there any official documentation of JavaMail which states the support of TLSv1.2?
I landed on following exception while using mail-1.4 jar in an java application to send mail:
javax.mail.AuthenticationFailedException: 421 4.7.66 TLS 1.0 and 1.1 are not supported. Please upgrade/update your client to support TLS 1.2. Visit https://aka.ms/smtp_auth_tls [PN1PR01CA0107.INDPRD01.PROD.OUTLOOK.COM]
To resolve above exception, I tried various versions of JavaMail. I could resolve my issue with the help of javax.mail-1.5.3 jar.
My query is there any supporting official documentation or blog which states to upgrade the JavaMail jar to version 1.5.3 or above?
Solution 1:[1]
The Jakarta Mail changes list (it lists changes including original SUN versions) does not mention TLS version support. But I do not think it should. That should be left to the TLS runtime that it is using as backend.
