I have a php script that automatically mails people with updates.

It is not spam.

I have been getting the AOL mails bounce back as suspected spam.
On looking at the message source the return path might be the problem. The following is part of the source.

Return-path: <wwwrun@desktop.norton>
Envelope-to: joebloggs@mailaddress
Delivery-date: Thu, 21 Aug 2003 12:12:34 +0100

I set Return-path in the php script as my email address but it the mail seems to actually pick up my machine on my domain as the return path. Is there any way of correcting this (it is not practical to change the domain - possible but not practical. Any suggestions much appreciated.

I didn't get a reply but on further investigation, if any one is interested. I have found that adding a 5th argument to the mail() function with the return path and an -f flag replaces wwwrun@desktop.norton as the return path with the variable ie
-f$myaddress variable. This only works in php 4.05 onward.
