When i send a mail report, it occurs the error: Mail from must equal authorized user

Is there something wrong in my mail configuration?

I haven't heard of this error message before (and hoped that we wouldn't have such indescriptive error messages).
But it seems like this is a message from your SMTP server, can you check if you used the correct email in the From field?

Hello @Findus23 ,

I encountered the same error and my analysis are as follows:

I captured packets with WireShark when sending an email report.

As we can see from the image, matomo uses the domain that matomo instance is running on with the "noreply@" prefix as the "MAIL FROM" field in smtp.
The SMTP server returned a 5xx error, indicates the mail from address does not match the authenticated user.

I tried to reproduce the error manually with telnet, and got the same error when providing a wrong MAIL FROM address.

I have fixed this issue and submited PR #14137
