SMTP server doesn't support authentication

1

Hello,

I’m getting SMTP server doesn’t support authentication message.  I checked the other postings/responses but my settings are correct:

Windows 10
IMAP: use SSL/TLS on special port (legacy) (port is 993)
SMTP: use SSL/TLS on special port (legacy) (port is 465)

I do receive messages but I’m getting these SMTP errors when I send.

Can anyone help?

The combinations for SMTP are:

Port 587 = Force usage of SSL/TLS
Port 25 = Use SSL/TLS if available
Port 465 = Use SSL/TLS on special port (legacy)

See if any of those work.
