Actually, to expedite the visibility configuration changes, it is generally
sufficient to do a "graceful" reconfiguration via "postfix reload". Or
just do nothing, and let the change take place incrementally as processes
"age out" (subject to $max_use and $max_idle) and are replaced.
Are the changes you're making so urgent that a restart or reload is warranted?
A restart disrupts existing inbound and outgoing connections (some mail may be
delivered twice), while a reload disrupts the queue manager, causing all active
mail to go back to incoming, and the active queue is then rebuilt.
If it is not an emergency, and it was working fine before the change, generally
best to let the change take place incrementally. You can reduce the latency
by reducing $max_idle to ~5s and perhaps take $max_use down to ~20 from 100.
