smtp_destination_recipient_limit is a feature of the queue manager,
not of the SMTP server, so it has no effect in the SMTP server.
I suggest using a dedicated master.cf entry with an smtp
client like so:
/etc/postfix/master.cf
pickup fifo n - n 60 1 pickup
-o content_filter=nullfilter:127.0.0.1:10025
smtp inet n - n - - smtpd
-o content_filter=nullfilter:127.0.0.1:10025
nullfilter unix - - n - - smtp
127.0.0.1:10025 inet n - n - - smtpd
/etc/postfix/main.cf:
nullfilter_destination_recipient_limit=1
Besides "-o content_filter" you will also need receive_override_options
somewhere as described in CONTENT_FILTER_README.
