Another weird case I ran into... infinite loops when the destination for the
$INBOX_DIR got full, and starting spamming the logs heavily (leading to
/var/log also getting full).

```
$ f=/var/www/archives.gentoo.org/.maildir/.gentoo-dev/.200209/cur/1032012623.011914.mbox\:2\,\:2\,S
$ PI_CONFIG=/etc/public-inbox/config \
ORIGINAL_RECIPIENT=gentoo-dev@lists.gentoo.org \
public-inbox-mda --no-precheck <$f
...

```

But the mail DID include a message-id:
```
$ f=/var/www/archives.gentoo.org/.maildir/.gentoo-dev/.200209/cur/1032012623.011914.mbox\:2\,\:2\,S
$ grep -i -e message-id $f
Message-ID: <Pine.LNX.4.44.0209141505570.24517-100000@kitt.york.ac.uk>
$ spamc <$f |diff $f -

```

The -watch instance kept looping as well, printing the random Message-Id between mails.
```
# grep path: ./public-inbox-watch.gentoo-commits.stderr.log  |uniq -c | tail -n4
      1 path: /etc/public-inbox/maildir-root/.gentoo-commits/.202101/new/1609861031.6347_0.finch
