Not all members included in the members-nnnn email list

Some members who where receiving emails when using members-nnnn@toastmastersclubs.org stopped receiving emails. They are still active members. They do receipes other emails from the toastmastersclubs.org domain. Can I see who all are included in members-nnnn@toastmastersclubs.org? How should I debug this?

Need club number then we can get you the list

The club number is 873616.

Check for a PM from me on this particular topic.

I have two members, husband and wife team, with emails address with same host. I can send emails to them from my gmail but the freehost emails don't make it to them. The email checker has flagged them as 'Bad'. I have send you a private message with the emails having issue.

You didn't post the your club number so it will be difficult to assist you.

If you want assistance in a timely manner post the first names of the people in question.
