I seem to recall that the OP is using Postfix 2.11 which does not
have that feature. :-(
As for smtpd_reject_footer it is expanded via smtpd_expand_lookup()
which contains the comment:
/*
* Don't query main.cf parameters, as the result of expansion could
* reveal system-internal information in server replies.
*
* XXX: This said, multiple servers may be behind a single client-visible
* name or IP address, and each may generate its own logs. Therefore, it
* may be useful to expose the replying MTA id (myhostname) in the
* contact footer, to identify the right logs. So while we don't expose
* the raw configuration dictionary, we do expose "$myhostname" as
* expanded in var_myhostname.
*
* Return NULL only for non-existent names.
*/
So it seems that using master.cf overrides of the generally recommended
form won't work here... :-(
