"Not a Member" Confirmation emails with no provocation

Sporadically, some of our members receive one or more Not A Member confirmation emails after having received emails routed through Members@ distribution list. It is not consistent and targets different people. It is disconcerting for our members to receive these. 

Why is this happening and what can I do to fix it?

Are they all using the same email processor?
YOu can turn off the link in email security.

We just use the members@, officers@, president@ etc distribution lists.

I turned it off. While I was in there, I put one of our members on the white list so Google recaptcha will stop flagging them as possible threats.

Thank you for your help, Brian.

I mean which email service do this members who have issues use?
Hotmail or some other free mail service?

Brian & Nancy, I believe this is a bug within ToastHost and not an issue on the recipient's end. I, and several other members of my club have received the same email that Nancy mentioned below. The timing of the email send appears to correlate when a user is on the website. For example, I emailed the meeting agenda to all members directly through ToastHost the email with the subject line, "Please confirm you are *not* a Member of Club 1098516 now" hit my Outlook inbox first, and received the meeting agenda message two minutes later.

Earlier this week, another member signed up for a meeting role and it coincided with members receiving the "Please confirm you are *not* a Member of Club 1098516 now".

I have logged into the Admin Console/Membership Management to confirm these members are still included on the 'Members' tab.

Please see attachment of the email we are receiving.

We are also facing this issue.
