# $mailprog defines the location of your sendmail program on your unix #
# system. (For FreeBSD, change this to "/usr/sbin/sendmail".) #

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

# $mail_admin defines the e-mail address that should be used as the #
# SMTP envelope sender address. This will be the address to which #
# FormMail-generated messages will be bounced if they are ever found #
# to be undeliverable for any reason. NOTE: This should be some #
# e-mail address that is ROUTINELY and FREQUENTLY monitored. #

# NOTE! NOTE NOTE! RFC 2821 absolutely _requires_ every mail server to
# have a working postmaster e-mail address. If you don't have one then
# for God's sake GET ONE! This means YOU!

$mail_admin = "postmaster\@dns20.com";
#You can replace this above address with your own or leave it as is. 
#This is where attempted abuse alerts will be sent.

# @recipient_addresses defines the e-mail addresses that e-mail can #
# be sent to. This must be filled in correctly to prevent SPAM and allow #
# valid addresses to receive e-mail. Read the documentation to find out how #
# this variable works!!! It is EXTREMELY IMPORTANT. #

@recipient_addresses = ("maryd\@spindesign.net","info\@profitsearchinc.com","dreed\@spindesign.net","dreed\@dreed.com");
#Please note the slash that MUST BE placed before the @ sign.
#If you only use one address, delete the 2nd one. If you send to more than 2, add them in the same format.

# @recipient_domains defines the e-mail domains that e-mail can #
# be sent to. This must be filled in correctly to prevent SPAM and allow #
# valid addresses to receive e-mail. Read the documentation to find out how #
# this variable works!!! It is EXTREMELY IMPORTANT. #
