[An on-line version of this announcement will be available at http://www.postfix.org/announcements/postfix-3.4.4.html]
Postfix stable release 3.4.4 is available.
Andreas Schulze discovered that reject_multi_recipient_bounce was producing false rejects with BDAT commands. This problem already existed with Postfix 2.2 smtpd_end_of_data_restrictons. Postfix 3.4.4 fixes both.
You can find the updated Postfix source code at the mirrors listed at http://www.postfix.org/.
