I have an Optus email account with Mozilla but I cannot send emails to anyone with a Yahoo account as they come back after five or six days or else just vanish.
Emails sent to people with Yahoo accounts don't go through. Some are returned after four or five days and others just vanish and never arrive with the recipient or come back to me. I do not have my own Yahoo account.

When they bounce, what is the error message that comes back with them? It would not surprise me at all is Optus were black banned from Yahoo for sending spam.
