Problem with return Path

[tsrwebman]

I downloaded a configured version today (7.11). Put it on my website and bingo - it worked - magic.

Closer examination however showed that the return path seems to be incorrect. It does not have the 'from' address - instead it has an 'administrator' value - telfordsteamrailway.co.uk@hosts.co.uk
which is nonsense.
So using 'reply' works - picking up the 'from' address
however my email server auto reply doesnt as it picks up this bogus address in what I believe is the 'Return Path'
I tried turning on SET_SENDER_FROM_EMAIL and SENDMAIL_F_OPTION
as in http://www.tectite.com/vbforums/showthread.php?t=1231

did I miss a config option?

help appreciated

Now this is definately silly

I have
define("SENDMAIL_F_OPTION",true);
define("SENDMAIL_F_OPTION_LINE",__LINE__-1); // don't modify this define("SET_SENDER_FROM_EMAIL",true);
in the formmail.php file.

I have
<input type="hidden" name="email" value="me@me.entadsl.com" />
<input type="hidden" name="mail_options" value="FromAddr=me@me.entadsl.com" />
in the form

and I get

Return-path: <telfordsteamrailway.co.uk@hosts.co.uk>
From: me@me.entadsl.com
Sender: Site Administrator <telfordsteamrailway.co.uk@hosts.co.uk>

Any help appreciated

I tried the testmail3.php file given in another thread
it didn't work so I guess I am stuck with an ISP with
settings that dont permit this

Ah well.
