The default behavior of UIview and APRSplus is the same as you described -- 
local messages only in either direction.   UIview has an optional white list to 
pass everything from specified stations (callsigns+SSID), but it can only be 
manipulated by directly editing a .ini file.  There is no access from the usual 
GUI user interface, which tends to discourage casual users from enabling this 
feature.

APRSpoint has no igate functionality of any kind at all.  [It can connect to 
the APRS-IS to drive the local mapping display, but it won't pass heard-on-RF 
packets to the IS.]

The HF PSK-63 APRS Messenger app supports per-callsign throttling per minute 
such as you are considering.

The now-dead WinAPRS supports igating (it was the original gateway app for the 
APRS-IS decades ago), but I don't know if it even does reverse-gating at all.
