After upgrading and configuring the script, everything is working fine except:
Neither the admin or the reserver are receiving the email confirmations. My settings:
$gen_email_admin = "YES"; # "YES" or "NO"
$gen_email_user = "YES"; # "YES" or "NO"
Since I am on a Unix server, I found this area and changed it from the default NT config:
use Socket; # <--
$AF_INET = AF_INET; # Use these 3 lines for UNIX servers.
$SOCK_STREAM = SOCK_STREAM; # <--
#$AF_INET = 2; # Use these 2 settings for NT servers.
#$SOCK_STREAM = 1; # <--
but that didn't help either. The following Sendmail config is correct as it works in other scripts:
$gen_email_method = "SENDMAIL"; # "SENDMAIL" for Unix servers or "SOCKETS" for NT servers.
$gen_sendmail_path = "/usr/sbin/sendmail";
I'm glad to hear that it is working for you now:
