Doing something non-trivial (other than manual administrative release
via "postsuper -H" on report of a false positive) is a programming
exercise for the administrator. There's nothing fancy built-in.
* You can use "postqueue -j" and "jq" to select particular messages
from the hold queue, based on the reported features.
* You can use "postcat -q [-ebh]" to examine the message content.
* You can move the message into the incoming directory (must reside
in the same filesystem!) of some other Postfix instance, which
might then deliver it in some special way (a per_recipient
maildir perhaps). With the messages stored in standard *822
format, it can be easier to write tools to do further automated
processing. But this could be more easily achieved with FILTER.
