I saw same error in my WordPress.
I solved by these code in my functions.php
add_filter( 'wp_mail_from', function() {
return 'wordpress@[MyDomain]';
} );
see https://github.com/Automattic/vip-quickstart/issues/512#issue-165799484
It’s maybe related to web server settings.
Right, it is not gtmetrics bug. Thanks for pointing me the solution.
Nevertheless the plugin is quite old and an update would be needed.
thanks for the codes @ functions.php .. it works
I had this problem too. I think you will find it’s triggered by the server_name being set incorrectly, or generically. If you make sure it is explicitly specified, the problem should go away. This also applies to proxies, so make sure the proxy isn’t processing every domain by default.
Hi we are seeing multiple errors with a similar header and expect this to also be an issue with phpmailer
Fatal error: Uncaught exception ‘phpmailerException’ with message ‘Invalid address: (setFrom) ____@https://____.com
we have recently changed our site over to https and note that if we revert back to http we don’t have the error. Any idea’s?
I just changed to HTTPS today and voila, I have this error. It happens to me when I update a user’s account, like resetting a user’s password. Going to try the functions code above shortly.

Hi,
I have the same error. I tried the below code in my site :
add_filter( ‘wp_mail_from’, function() {
return ‘wordpress@[MyDomain]’;
} );
But it is not working.
Please help.
