The tcp daemon should probably exit when the postfix client disconnects. This will happen periodically as postfix retires and recreates new smtpd processes. The max connections will need to be at least $default_process_limit (default 100). Each smtpd process will create its own connection to your table. I suppose you could use proxy:tcp: to limit the number of connections. -- Noel Jones
