Is it possible in postfix to forward messages from the hold queue by referencing to them by their file name?
The best way would be by a terminal command.
Even better would be a python command.
If that's not possible editing the main.cf would be a considered option.
Background:
I have a python script which gives me a dynamic list of filenames of the mails in the hold queue which should be forwarded to a specific address for further examination before being delivered to their final destination.
e.g. of a file list from the hold queue
49C0B406D7
1F3BD40685
