Can't get this script working ! Can't Post

I try to get a "mailyourfriend about this site" script (Perl) going, but this newbe fails. I have installed this script (birdcast.cgi) on the web and after going to: www.deraarstesitevannederland/cgi-bin/birdcast.cgi the script comes nicely on my screen. But pressing the button "send" brings me to a site: http://yourdomain.com/cgi-bin/birdcast.cgi which is not my intention at all.
The script I use is:

#!/usr/bin/perl
use Socket;
$|=1;

# birdcast.cgi Version 2.0

##################################################################

# CONFIGURATION NOTES

#
# $SCRIPT_NAME is the full URL of this script, including the
# http part, ie, "http://domainname.com/cgi-bin/birdcast.cgi";
#
# $SITE_NAME is the "name" of your web site.
# $SITE_URL is the URL of your site (highest level)
# $END_LINE is the very last line printed in the e-mail.
#
# $MAXNUM is the number of possible people a person can refer
# your URL to at one time. If you call the script using the
# GET method, then this is also the number of entry blanks
# created for recipient names and addresses.
#
# $SMTP_SERVER is the name of your e-mail gateway server, or
# SMTP host. On most systems, "localhost" will work just fine.
# If not, change "localhost" to whatever your ISP's SMTP
# server name is, ie, smtp.isp.net or mail.isp.net

# $SEND_MAIL is the full path to your server's sendmail program
# If you do not wish to use Sockets for some reason and need
# to use sendmail, uncomment the $SEND_MAIL line and comment
# the $SMTP_SERVER line.

# okaydomains is a list of domains from which you want to allow
# the script to be called from. Leave it commented to leave the
# script unrestricted. If you choose to use it, be sure to list
# your site URL with and without the www.

# Use either $SMTP_SERVER
# $SMTP_SERVER="localhost";
#
# OR
#
$SEND_MAIL="/usr/sbin/sendmail -t";
#
# BUT NEVER BOTH!!!!!!

# @okaydomains=("http:// www.deraarstesitevannederland.nl", "http://www.deraarstesitevannederland.nl");

So, this was the script. Further info:
the path of Perl5 on my server is: !#usr/bin/perl
sendmail-path is: /usr/sbin/sendmail
As far as I know I set the correct cmod value for the attributes: 755 (owner: read, write, execute; group: read, execute; other: read, execute).
In the script there is something about a SMTP_server which I do not understand.

Could anyone help ?

Re: Can't get this script working ! [In reply to] Can't Post

Well, no, that was not the problem. I solved some of the problems but I still can't change the email message of this "birdcastscript" (downloaded from www.birdcast.com) I understand that I should be able to change the email message by changing the lines between "Stop of Mail"...... But I can change what I want but the email message remains the same !! What do I do wrong ? Further everything works ok ! I changed other parts of the script, no problem but this email message is not willing to adapt. At least not with me !
Can anyone help ?

Re: Can't get this script working ! [In reply to] Can't Post

I haven't had a good look at the script, but I have had a similar problem myself. My e-mail client was set up to keep a copy of messages received on the server. For some strange reason, it was downloading the same message each time. So I'd send, say, 1 message with the script, and then check my e-mail - message downloads fine. Then I'd send another, but my e-mail client would download the first message again. It took a very long and frustrating process to work that one out!

It's rather strange I know, but I thought it might help. Either that or perhaps something's being cached somewhere.

Thanks Lawrence,
but what do you mean exactly with "My e-mail client was set up to keep a copy of messages received on the server." ? And is there something I can do about it ?

Re: Can't get this script working ! [In reply to] Can't Post

Normally when you check your e-mail, you download all new messages onto your own computer, and they are deleted off the server. Many e-mail programs (such as Outlook Express), give you the option to keep a copy of messages on the server, rather than delete them.

However, if you don't know what it means, most likely you haven't set up your e-mail software that way! What e-mail software do you use?

It was just an idea that I thought I'd mention. Sounds like your problem may be a little more difficult to solve, and unfortunately, I don't have any other suggestions for you.
