You cannot use the Milter protocol to make a connection to Postfix.
Instead, Postfix makes a connection to a Milter when it wants to
receive ONE email message. the Milter can't use that connection to
send requests to Postfix about other email messages, and it would
not make sense to change that protocol.
The Milter application can know the queue ids, sender, and recipients.
Of course that information is also available with the postqueue
command. Use
postqueue -j | jq 'select(.queue_name=="hold")'
to get JSON-formatted info about quarantined messages.
You can use "postcat -qbh queueid" to look inside an email message,
and postsuper -H queueid to unquarantine it. Keep in mind that a
message will be released for all its recipients.
