Quick update: I've done a brain-dead simple, but correct, implementation
that always quotes the name (just like qmail, BTW). If needed, it
can be made smarter later.
There 's some draft documentation below.
Wietse
header_from_format (default: standard)
The format of the Postfix-generated From: header. By default, Postfix
generates this header only for clients that match the local_header_re-
write_clients setting.
This setting affects the appearance of email from programs that submit
messages without From: header, such as some /bin/mail command-line
implementations.
Specify one of the following:
standard (default)
Produce a header formatted as From: "name" <address>. This is
the default as of Postfix 3.3.
legacy Produce a header formatted as From: address (name). This is the
behavior prior to Postfix 3.3.
This feature is available in Postfix 3.3 and later.
