Message posted by Officer is not reaching the members

Messages posted to "members-1114237@toastmastersclubs.org" by one of our officer "Margie" is not reaching any of the members. The messages does not seem to bounce back too. I checked the e-mail address of Margie and it seems to be listed correctly in our club's web-site.

Can you please let us know what went wrong?

Thanks,
Shan
