Hi all,  
I need a help.  
An error is occurring when sending a test email.  
See the error:

Sending failed for one or more recipients

What can it be?

With best regards,

Hello, and welcome to the forum.

Most likely you don’t have a valid sending method.  
For example you are using Amazon SES, but you didn’t verify the sender email in question.

Good luck,  
Joey

Hi joeyk,  
All right?  
I also tested with another smtp from the company where I work.  
It also didn’t work.  
Do I have to parameterize anything else in mautic?  
Thanks

Hi joeyk,  
I tried to send an example.  
But I didn’t receive the email.  
Could you show me how you set it up in your environment?  
Print the configuration.  
Thanks.

What SMTP will you use?

- Your own? Amazon? Sendgrid? Other smtp?
- Are you trying to connect to your own mailbox?

Hi Joeyk,  
I am using my own smtp.  
Authentication is successful.  
However, when sending test email the error message occurs:  
Sending failed for one or more recipients  
Thanks.

Yes of course.

You have multiple problems:

- inode limits exceeded or mb full or disk full
- your host doesnt allow you to send unsolicited emails - did they block you?

I would just move.
