Note, instead of forcing random contortions on clients, a server that
wants to enforce this feature should simply reply with 421 to RSET after
100 transactions, and Postfix will politely abandon the connection and
try a new one.
Also, forcing a new connecting on an MTA with a decent reputation wastes
resources on both ends. Artificial limits should only be applied to
suspected abusive sources. If you're not on their whitelist, they have
one, and you're eligible, that may be a sensible work-around, provided
whitelisted hosts are not subjected to silly limits.
