Emails sent via the FTH site arrive with the wrong name as sender

Emails sent via the FTH site arrive with the sender:-
Toastmasters Club 398 on behalf of Tracey Lane CC CL
Tracey Lane is a former member and is not the sender of these emails.
Our FTH website is -
gleninnes.toastmastersclubs.org
Can you help

it is your email client that is assigning the wrong name,
Your email client is assigning a name based on who sent from server@toastmastersclubs.org

Thank you Brian
What can I do about that?
It is not only my emails that have the wrong sender but the president of our club’s emails have the same problem.

I would need to know what email client you are using? Hotmail, gmail, yahoo etc

Then you need to search on google for "wrong name associated with email address", it has to do with what name your email client has attached to that email address. basically you need to create / change the contact for that email address.
