[Fetchmail-devel] logging Message-Id header from fetched messages?

[<nr...@cs...>]

In an attempt to diagnose some problems with mail delivery,
I looked to my logs to see what messages fetchmail had fetched.
Fetchmail does not appear to log the incoming Message-Id header,
even with debugging turned up (fetchmail -vvv).

Running
   env LC_ALL=C fetchmail -V -v --nodetach --nosyslog 
as recommended in the FAQ turns up the information that
  Idfile is /home/nr/.fetchids
but this file does not exist.
I am running fetchmail from the command line, as myself, so the
directory should be writable.

I am running a fetchmail built from the git repository whose latest
commit is

  commit 5aaa3cec988329f11d27911aa3994f4776139c0b
  Author: Matthias Andree <mat...@gm...>

      Document use of address literals for SMTP.


After consulting the FAQ, I hope my situation is covered under

  G4. I have this idea for a neat feature. Will you add it?

I would like for fetchmail to log the Message-Id of each message fetched.
I think it would be a good default, but I am certainly willing for it
to be available through a configuration option or command-line option.

I cannot find instructions about how to proceed.  My best guess was to
subscribe to and write to fetchmail-devel.  A request for a new feature
is not a bug report, but if desired, I can gather the information
appropriate to a bug report.
