indent_switch.php::on_smtp_connect() (version 4.0.1)

[F D]

‌

154: if (!is_integer($iid) || $iid == -1)

does not work on PHP 7.3.13 with a $iid == 6. I suggest to change to

‌

154: if (empty($iid) || $iid == -1)

additionally it would be great to give admin a chance to control data from line 184 were written to log file (this currently included password in clear text which is not very nice).

‌

##          self::write_log(print_r($args, true));
