I tried that command from http://neilswartz.com/FormMail/formmail.php?testalert=1 and
http://localhost/Work/PHP/FormMail/f...hp?testalert=1 with 2 different DEF_ALERT addresses. I also added these two e-mail addesses to TARGET_EMAIL.
The DEF_ALERTs recieved no e-mails. I've also downloaded & run testmail.php & testmail2.php. Both ran successfully. And finally I tried using the alert_to parameter - still no auto response or error e-mail.
This is nolonger as serious problem as before - I've convinced my user not to use auto response. But, I still would like to get it to work.
