I’m trying to use OVH.
Everything works fine but when I try to send two test mail one after the other I get the first delivered while the second not.

I’ve asked for help to the hosting help desk they tell everything is fine on them and maybe the script I’m using for mail send is making too much requests while hiding them in the logs.

Please help.

Here you can find a link to the form

Thanks

@somsookheimwee

From your web hosting:
Note that the “From” address must be an active email account on your domain with One.com, and must match the email account used for the authentication.

@carletto0282
Did you use your full OVH email address?

@yehudah:

When people post reactions, they do not have an email that comes from my domain. Yet, I do want to receive notifications obviously.

Further, all my settings are using the same emailaddress: [email protected]. Which is the admins email, the wordpress email, the email im using in my smtp settings, the enveloppe email and the username for authentication email.
This is a working emailadress Im actively using. The problem must be something else, no?

@yehudah

The from email address is a fully functional email account.

The same error occurs even when sending to external addresses… take a look here

@yehudah any answer for me?

@somsookheimwee

So sorry, I was sure I answered you.

In SMTP protocol, Error 551 is shown when a sender is not found to be authorized to relay mail through the server. This is a strategy to combat spam.

In your case, either the Sender’s Email Address or the Recipient’s Email Address should be hosted on the SMTP server.

In your log, the recipient is: [ redacted ]

This is server-side issues and what I wrote it’s my opinion.
I highly recommend getting more details from your web hosting support.
