You may wish to configure your list so that it becomes a moderated one. A moderated list is one where postings to the list are checked before being passed onto the list.
If you have not already done so, please login to the web interface.
On the left hand side you may see a number of lists you own and a number of lists of which you are a member.
Select the list you want to moderate by clicking on the blue "Admin" icon beside it.
Click on "Edit list config", then click on "Sending/receiving setup".
Under "Who can send messages" click inside the box and select one of the options which contains the word "moderated".
Once you have chosen, scroll down to the bottom of the page and click on "Update" to commit changes.
Please bear in mind, if a moderated list has no moderator, then the postings to the list will go to the list owner(s) for approval instead.
If you do not wish to receive these messages, then you must add a list moderator.
