Since last night my emails in 3 accounts won't send in thunderbird. I get the following message

the message could note be sent because connecting to the outgoing server SMTP mail.optusnet.com.au failed. The server maybe unavailable or is refusing SMTP connections. Please verify that your outgoing server (SMTP) is correct and try again.

The provider Optus has confirmed it doesn't have any issues.

Is there a problem with this with Windows 11 which i have just downloaded 5 days ago?

Does anyone have any suggestions?
