<p dir="auto">The second row in your screenshot needs to specify <strong>Any</strong> instead of <strong>All.</strong> Your current set of conditions is satisfied only if the List-ID > Identifier contains all of the digits 0-9.</p>

<p dir="auto">Unfortunately, the choice of operators doesn't include "does not start with" alongside <strong>does not contain.</strong> Someone who knows more than I do might be able to tell you whether the match field at the end of each row accepts regular expressions that could specify the beginning of the List ID string.</p>
<p dir="auto">Although you didn't ask, I'll also add that these automatically generated mailboxes can be renamed like any other mailbox. My own practice is rename unintelligible List-ID mailboxes with something readable that lets me know their nature (e.g., "3238652052BM" becomes "Asustor"). A leading character can force the mailbox to the beginning or the end of the list. When all the messages with that List ID are deleted, the list mailbox will disappear as well.</p>
