[An on-line version of this announcement will be available at http://www.postfix.org/announcements/postfix-3.2.4.html]
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.
