Sorry for double post, but i got this error when i try to send an email :
550 Please turn on SMTP Authentication in your mail client

I see an MX record of _dc-mx.dda14cdca925.thomasfds.fr. still being returned along with your new correct mail hostname. This is a synthetic record generated by Cloudflare when the MX record points to a proxied host. I would have expected it to go away once you updated your MX record to use an unproxied hostname. You may want to check for any extra MX record and remove it if found. If you still see the synthetic MX hostname, you might try removing all MX records for at least 5 minutes and then add back only your new DNS Only hostname.

when i try to send an email :
550 Please turn on SMTP Authentication in your mail client

That message is from your o2switch mail server, and the error is letting you know that you will need to use a username and password in your outgoing email settings. Be sure that you use TLS on any connections where you send credentials.

Sorry i don’t have read when i have write about error 550, it’s when i try to receive an email send from another email, exemple i try to send email from [email protected] to [email protected] and i got the errror 550.

and at now emails work greats without any actions from me… so it’s nice …
