Fredrik Jonson commented on GERONIMO-6792:
------------------------------------------
After RFC 8996 - Deprecating TLS 1.0 and TLS 1.1 - was published in march 2021,
I have noticed that some mail providers indeed now disallow TSLv1.0. This
obviously makes the current release of geronimo-javamail fail delivery to such
RFC-compliant servers.
I have locally built and manually tested the patch
GERONIMO-6792-v4-no-hardcoding.diff. I can confirm that it by default selects
the default TLS protocols of the JVM, which is a great default behaviour btw. I
have also tested using the mail.smtp.ssl.protocols flag, with various protocol
versions, and it appears to also work as intended.
Is there anything else a non-committer can do to help nudge this into a proper
(1.0.1?) release sometime soon?
PS. A big _Thank you_ to Richard W for finding the bug, and proposing a patch!

> Hi,
> I encountered some issues when using Geronimo Java Mail 1.6 (1.0.0) bundled
> with TomEE 8.0.5. The related thread [1] can be found on the
> [us...@tomee.apache.org|mailto:us...@tomee.apache.org] Mailing-List.
> In short:
> * Our mail server does only support TLS 1.2 or TLS 1.3
> * Geronimo Java Mail 1.6 in version 1.0.0 has TLS 1.0 hard-coded in the
> source and does not use the default protocols or the specified ones via
> *mail.smtp.ssl.protocols* for a TLS connection.
> I have attached a patch created via SVN DIFF.
