please post your club number in every post that way we can see that you are doing.

My club number is 687847.

Which officers email address are you trying to send to?

what is the exact address you are sending to?

Mr. Brain,
Actually we are trying to send our club officers mail ids which are giving below but the problem is not only for me everyone is facing the same problem:
president-687847@toastmastersclubs.org
vped-687847@toastmastersclubs.org
vppr-687847@toastmastersclubs.org

We are unable to understand what was happened?

Those email address do not exists as the site admin has not assigned members to those positions.

The valid club email addresses are list on the left menu click on the "Club E-mail Addresses "
