PHPMailer.php

From A2Wiki

Regarding the instruction to use the "-f" parameter when sending mail from a PHP script:
"Make sure you properly set a proper envelope sender using the '-f' parameter with the php mail() command or with sendmail."

• A2 Hosting Knowledgebase - How to properly set the 'From' address

Because I am using the PHPMailer.php class to deliver my emails I wasn't sure at first what was meant. I searched inside the class and found references to -f, which sets the sender.

If using Sendmail:

function SendmailSend($header, $body) {
if ($this->Sender != "")
$sendmail = sprintf("%s -oi *-f *%s -t", $this->Sendmail,
$this->Sender);
else
$sendmail = sprintf("%s -oi -t", $this->Sendmail);

And if using Mail:

function MailSend($header, $body) {
...
if ($this->Sender != "" && ...
{
...
ini_set("sendmail_from", $this->Sender);
$params = sprintf("-oi -f %s", $this->Sender);
...
}

Basically, you want $this->Sender to be set.

The result will be that the Return-path in the email source should be explicitly set so that it doesn't default to "nobody" at the web host.

i.e. not
