That's the only value needed. Whoever built your package decided to
disable the ESMTP CHUNKING extension (aka BDAT). If you want/need
BDAT, you'll need to s

complain to your vendor.
Otherwise, how many (Postfix) master daemons are there on your system?

Hi Viktor,
Maybe so. Here is output from postconf containing "discard_ehlo_keywords":
# postconf | grep discard_ehlo_keywords
postscreen_discard_ehlo_keywords = $smtpd_discard_ehlo_keywords
smtp_discard_ehlo_keywords =

smtp_discard_ehlo_keywords
possibly via master.cf overrides?
