Changes between Initial Version and Version 1 of Ticket #64368, comment 8

initial	v1
1		I've found the solution to this problem. After reviewing Sendmail and PHP code, I was trying to understand how the Sender processing was being done, as it made no sense to me (plus the `sendmail_from` thing). I thought that the problem was that it was adding a `sendmail_from` but this was irrelevant. It's true that having a `sendmail_from` set up, will set it as the Sender envelop but not because of PHP default behaviour but a PHPMailer casuistry that is not relevant to this specific problem.

3	3	The thing is that all issues fall into PHPMailer: it was basically double-setting the `-f` parameter if the `sendmail_path` was set (as many had, and as it is a recommendation by the PHP docs).
