Changes between Initial Version and Version 1 of Ticket #54465, comment 1

-              initial
+              v1
 So basically, here is that this address `nameSurname.@gmail.com` is not valid.
+[https://github.com/PHPMailer/PHPMailer/blob/0ff2d3c8ead628df2493537d9f91db962aa47718/src/PHPMailer.php#L1638 If you check PHPMailer code] basically its failing to spot a to, a cc or a bcc because [https://github.com/PHPMailer/PHPMailer/blob/0ff2d3c8ead628df2493537d9f91db962aa47718/src/PHPMailer.php#L1105 its unable to find a valid address] with an @ because of that dot,
+Maybe you could find some help with this little workaround: I was able to bypass this by setting the `wp_mail_from` filter like this:
+{{{
+add_filter('wp_mail_from', function($original_email_address) {

+});
+}}}

 …
 Date: Sat, 12 Jul 2025 17:25:56 +0000
 To: nameSurname.@gmail.com
 From: WordPress <wordpress@mailhog.local>
+From: WordPress <wordpress@server.local>
 Subject: Subject
 Message-ID: <nUcLDNeY6tTDsDB3ReQB88Sfd3pQrxN0QRugoMqqR4@localhost>
 …
 }}}
 The email, although, is being delivered with `wp_mail` despite not being compliant.
+The email, although, is being delivered with `wp_mail` despite not being compliant. So I don't recommend you using an email like such
 Closing this for being `invalid` for not compliant with the RFC.
