How to set up sendmail path?

[chan21]

My autoresponder software asks sendmail path. This is the path: /home/username/mail/sendmail. I have already completed home username and mail. But I couldn't replace sendmail path.I asked my hosting provider what the sendmail path is.He has provided me this information.
outgoing server name: mail.diet-weightlossonline.com
Port: 25

Now I have set up Mozila Thunderbird. Thunderbird is working well.(out going and in coming mail) This is the smtp server name: diet-weightlossonline.com Could you please tell me what is the sendmail path I should provide to my software. Please kindly any one help me.

There's a simplest way to deal with Email form. See the
details at Learning PHP in 10 Minutes, then modify the template into your own form.

I don't want to contact form.I want to set up my software. this is the software.
# Type the URL address of the ar.cgi.
# Replace ONLY www.yourdomain.com to yourdomain or URL address.

$scriptpath="http://www.yourdomain.com/cgi-bin/autoresponder/ar.cgi";

$htmlpath="http://www.yourdomain.com/html";

$imgpath="http://www.yourdomain.com/html/img";


# Type the full path to your EMail program.
# If you're not sure of this, ask your server administrator

$mailprog="/usr/sbin/sendmail";

# Type your email address. Make sure
# to place a \ in front of the @
# As an example: admin\@autoresponderunlimited.com

$fromaddr="admin\@autoresponderunlimited.com";

# This is the file that will hold all of the email addresses and names
# of all of your autoresponders. Change it to something more secretive.

$mbase = "collect.txt";

# Type default name. If the system is unable to extract
# the prospect's name, it will print the Default Name.

$emptyuname="Friend";

# Enter the Admin password (case sensetive 8 chars max)

$password="password";
