https://lists.exim.org/lurker/message/20170102.153501.d4c71d99.en.html
(January 2017) says that we are dropping support for openssl v1.0.1
and below.

https://www.openssl.org/policies/releasestrat.html says:
   With regards to current and future releases the OpenSSL
   project has adopted the following policy:
     The next version of OpenSSL will be 3.0.0.
     Version 1.1.1 will be supported until 2023-09-11 (LTS).
     Version 1.1.0 will be supported until 2019-09-11.
     Version 1.0.2 will be supported until 2019-12-31 (LTS).
     Version 1.0.1 is no longer supported.
     Version 1.0.0 is no longer supported.
     Version 0.9.8 is no longer supported.


Is it time to announce when exim will drop support for
openssl 1.0.2 and 1.1.0 ?

Not sure from that whether Postfix 3.4 supports OpenSSL 1.0.2 ?

Red Hat Enterprise Linux 6 is stuck with OpenSSL 1.0.1, but is on its
last legs (entered "Maintenance Support 2 Phase" May 2017 and will be
retired November 30, 2020) so I hope that its users will be moving the OS on
and not in great need for the latest exim features.
