How to change envelope sender address using phpmailer?

Question

With php mail() I can write

mail(\'to@example.com\',\'subject!\',\'body\',\'From: from@example.com\',\'-f from@example.com\');

But how can

Answer 1

What worked for me (obscurely) using

$mail->SetFrom('name@yourdomain.com', 'Rupert Bear');

was to use localhost rather than directly access the smtp server e.g.

$email->Host='localhost'; // SMTP server this way you get from name (don't know why)

Now mails arrive in Outlook from 'Rupert Bear' [name@yourdomain.com]
