I have an issue with mailman v2 where messages are coming in to the service but
not coming out. The error logs report:
Aug 30 18:47:26 2024 (9118) send_digests() failed: maximum recursion depth
exceeded
and an occasional:
Failed to unlink/preserve backup file: *.bak
>From the oldest recoverable logs (before they rotated and got removed) I also
>have:

How do I go about finding and correcting the issue?
