This announcement concerns fixes for problems that were introduced
with Postfix 3.0 and later. Older supported releases are unaffected.
Fixed in Postfix 3.1 and later:
* DANE interoperability. Postfix builds with OpenSSL 1.0.0 or
1.0.1 failed to send email to some sites with "TLSA 2 X X" DNS
records associated with an intermediate CA certificate. Problem
report and initial fix by Erwan Legrand.
Fixed in Postfix 3.0 and later:
* Missing dynamicmaps support in the Postfix sendmail command.
This broke authorized_submit_users settings that use a
dynamically-loaded map type. Problem reported by Ulrich Zehl.
