Cannot Send Mail

[ginawhite]

Using a non-TPG email address. It has been working fine for months. Stopped working yesterday. Error message is "Cannot send mail - the server rejected one of the recipient's addresses. The message has been placed in your Outbox".

Using MacBook Pro, iPhone XR and iPhone 12 - the standard Apple Mail account. 

Incoming Host name:  mail.optusnet.com.au

Outgoing Host name: mail.tpg.com.au

Port: 25

Are these settings correct?

Thanks

Gina
