V5.4.9: wp_mail_failed triggered on Invalid address: (setFrom)

Hello,

MOU V5.4.9 does not send emails.

After some debug I found out that the way $from is now constructed makes wp_mail_failed trigger on the setFrom field.

[errors] => Array
        (
            [wp_mail_failed] => Array
                (
                    [0] => Invalid address:  (setFrom) <server name here>
                )

        )

It happens whatever the server name (simple localhost, hosted primary domain, hosted sub domain).

WP4.9.1 + LAMP PHP 7.1.9 – hosted primary domain
WP4.9.1 + LAMP PHP 5.6.31 – hosted sub domain
WP4.9.1 + LAMP PHP 7.2.0 – local dev localhost

Current applied workaround :
wp_mail($this->mailonupdate_listOfCommaSeparatedRecipients(), $subject, $message, $headers);
replaced by
‘$MailResult = wp_mail($this->mailonupdate_listOfCommaSeparatedRecipients(), $subject, $message, $headers);

if ($MailResult != true) { // Rollback to V5.4.8 method
$sender = ‘WordPress@’ . preg_replace(‘#^www\.#’, ”, strtolower($_SERVER[‘SERVER_NAME’]));
$from = “From: \”$sender\” <$sender>”;
$headers = “$from\n” . “Content-Type: text/plain; charset=\”” . get_option(‘blog_charset’) . “\”\n”;

$MailResult = wp_mail($this->mailonupdate_listOfCommaSeparatedRecipients(), $subject, $message, $headers);
}`
