Environment

  • Liferay DXP 7.0
  • Liferay DXP 7.1
  • Liferay DXP 7.2
  • Secure (TLS) mail server

Resolution

  • The issue comes from an outdated javax.mail library in current portal versions. The javax.mail library Liferay uses doesn't support TLS v1.2, it only supports TLS v1.x.
  • As such, mail servers which don't offer TLS v1.1 and 1.0 can't be used to send mail from Liferay DXP.
  • The resolution is documented on LPS-114513 and is currently being reviewed. If you can't wait for an official fixpack, please open a support ticket mentioning you need the fix for LPS-114513 and provide your current patchinfo.

Additional Information

  • LPS-114513: Upgrade javax.mail to 1.6.2 to be able to use mail.<prot>.ssl.protocols
