member previously had another email whose vendor was indeed blocking mail but changed to a valid and verified gmail account. ... yet is getting this warning again

Are they clicking unsubscribe instead of delete by chance? Anything other than a non-successful delivery will trigger this so that includes an unsubscribe and then a transactional email attempt.

Not sure I understand your response.

After receiving initial warning, Member updated email and verified new email address with successful account login. Message disappeared. Member made no changes to notifications but lockout message reappeared several days later.

So to restate the issue, member did have an email that was being rejected. They changed to a Gmail account and the message went away initially and all was good. However, it has returned. But again, this is a generic gmail account. We are a bit stopped as to why this one member / invision email has an issue with Gmail.

It’s possible the user has a workflow that is either reporting the messages as spam or unsubscribing. If it is happening with ONLY one user and multiple addresses… it’s something the user is doing.

first email WAS being rejected and was confirmed by email vendor ... second is gmail... verified as receiving mail sent to account.... checked user notifications , no email now requested. One explanation is member 'lied' about the the warning going away ...i.e ignored the email about resetting the account, just changed the email. The problem is how to resolve without a third address.

We would need to know the details to take a look. Its not possible to know without that. If you can provide me with the email via PM, I can take a look for you
