WordPress 7.0 inclusion of PHPMailer 7.0.2 breaks .user.ini override of sendmail_from

Description

I have created a ticket on PHPMailer here: https://github.com/PHPMailer/PHPMailer/issues/3342

But the gist is, the recent patch in PHPMailer 7.0.2 prevents the .user.ini from overriding an existing -f flag in the sendmail command. Which prevents sites from fixing the incorrect domain on certain hosts (like Nexcess/LiquidWeb) and causing all mail to no longer be deliverable. I have a workaround for now with this simple patch, but ideally PHPMailer needs to be fixed in order to allow the flexibility to override the default sendmail command.

Here is my workaround:

<?php
add_action('phpmailer_init', function ($phpmailer) {
    $phpmailer->isSendmail();
    $sendmail_from_value = ini_get('sendmail_from');
    if (empty($sendmail_from_value)) return;
    $phpmailer->Sender = $sendmail_from_value;
}, 999);

Milestone Awaiting Review → 7.0.1

Putting in the 7.0.1 milestone for tracking, but fixing this will be dependent on an upstream release

Milestone 7.0.1 → 7.0.2

As the RC for WP 7.0.1 is expected to land tomorrow we'll have to punt this to 7.0.2.
