Disable the 'not a member' message that was recently appended to emails

Is there a way to disable the "Not a member? Use this link if you are no longer a member of this club . . ."  This message is not necessary and just lengthens the email to our members.  I have heard a number of complaints about it.  Is there a way to disable/suppress this message?  I have members post to the list if they want to be taken off of the email distribution list, which works fine.  Thank you.  I really do enjoy your site and am so appreciative of the work the team at Toastmastersclubs.org does!

It can be disabled via a setting in the Email and Contact Forms admin module...  Scroll down on the Email Security tab:  support.toastmastersclubs.org/doc/item/reducing-spam
