Bad link in mailman

Hi, My Mailing-List current/default settings prevent me sending a "large" email, which is fine (I use links rather than attachments. Unfortunatelly I sent an email via the Mailing-List that had accidently had an attachment and I received this email:

Subject:	1 "Mailing-List name" moderator request(s) waiting
Date:	Wed, 25 Nov 2020 08:00:13 +1100
From:	"mailing-list name"='motorkhana.competitors-bounces@motorkhana-wa.com'>-bounces@domain.com
To:	"mailing-list name"='motorkhana.competitors-owner@motorkhana-wa.com'>-owner@domain.com

The "mailing-list name"='Motorkhana.competitors@motorkhana-wa.com'>@domain.com mailing list has 1 request(s) waiting for your consideration at: Please attend to this at your earliest convenience. This notice of pending requests, if any, will be sent out daily. ------------------------------------------------------------------------------------------------------------------------------------------------------- The above link resulted in a 403 error. I had to manually log-on to cPanel and go to the Mailing-List management page.
