Hi Community,

I attempted to configure an outgoing SMTP email server using OVH with the following parameters:

• Authentication Method: Username
• Connection Encryption: SSL/TLS
• SMTP Server: ssl0.ovh.net
• SMTP Port: 465
• Email: myemail@mycustomdomain.com
• Password: mypassword

I also defined mycustomdomain.com under Settings / Domain Aliases.

However, when running test emails, I consiInvalid Operation

Server replied with the following exception:
(535, b'Incorrect authentication data')
stently receive the following error message:

Could you please help me resolve this issue?

Alternatively, could you suggest a free SMTP server I can use to work around this problem?

I also tried using Gmail with OAuth authentication, but encountered the same error message.

Thanks
