How can I see if an email bounced back?

Hi There
Wandin Toastmasters has a dropbox account associated with the email address of treasurer-3011962@toastmastersclubs.org
Dropbox have been sending a 6 digit code to that email address but my treasurer tells me that she is not receiving any email from DropBox.
Are you able to see if that email address bounced the DropBox message?

Many thanks

You probably need to determine the sending address for Dropbox and add that email address to your club whitelist.   

Hi Steve
Thanks for the quick response. I have added the email addresses to the whitelist of the club. I've tried to login to dropbox again. No email arrives. Is there no way you can check for an email that has bounced?

Many thanks
Judy

Hi Steve
I tried adding to the whitelist without success.
Is there anyway that I can send an email (to dropbox) so that it says it is from treasurer-3011962@toastmastersclubs.org?

Many thanks
Judy

No, that would not be allowed.

Do they not offer to send by SMS to the phone number registered to the account?

Hi Brian
I don't know what phone number is linked to the account sadly!
