I've got a Linux server running sendmail.
A member signs up in my script. Each member is required to give a valid email address. One of my subroutines sends a message to the new member which verifies whether the address they gave is fully valid and accepting mail. I'm stumped! How can i ask sendmail to send a message and tell me if there was an error without crashing my perl cgi? I've tried MIME::Lite and sendmail. I don't want to mail/forward the error, i just wanted to see a command line reject/error statement. Is this possible? The end goal being a perl script which prints out to the new user a statement telling them there email address is not a valid resolving location and try again. I've tried an "or die" with the open statement below, but no luck. 
my %MAIL = ();
$MAIL{'TO'} = "NotAcceptingMail@remoteserver.com";
#Brevity exclusion here
open (SENDMAIL, '|/usr/sbin/sendmail -oi -t');
print SENDMAIL <<"EOF";
From:<$MAIL{'FROM'}>
To:<$MAIL{'TO'}>
Subject: $MAIL{'SUBJECT'}

$MAIL{'BODY'}
          
EOF
close (SENDMAIL);
