Comment (by siliconforks):

 One possible pitfall here is that it appears it is a common
 (mis)configuration to have `sendmail_path` in `php.ini` configured with an
 `-f` option.  If you do that, and then you specify a sender with PHPMailer
 (or if you just call PHP's `mail()` function directly while specifying an
 `-f` option), you end up providing the `-f` option to `sendmail` twice,
 which apparently causes `sendmail` to fail completely.

 This is mentioned in the PHPMailer wiki (see the part which mentions `More
 than one "from" person`):

 instantiate-mail-function
