Mod_Perl and Net::SMTP
I have a Netware server 6.5 sp6 with Apache 2.0.59. I am trying to use some perl scripts to send HTML form data back to a particular e-mail address. The scripts work on my workstation with my active perl but fail running on the server.
Error message:
Can't call method "mail" on an undefined value at sys:/perl/web/mailtest2.pl line 6.
It's always a line containing " $smtp = Net::SMTP->new("smtpserver")
I tried many different scripts but it always seems to be a problem around the object utilizing "Net::SMTP;. Is there a known issue with this. My version of MOD_PERL is 1.01.00

I got it to work after upgrading the TCP/IP stack. It works for awhile but after processing a few forms I get the following:
Failed to open SMTP connection: Inappropriate I/O control operation
Here's some test code I'm using to diagnose the problem.
#!/usr/bin/perl
use Net::SMTP;
#Create a new object with 'new'.
$smtp = Net::SMTP->new("10.102.10.74");
if ( ! $smtp ) {
die "Failed to open SMTP connection: ", $!, "\n";
}
#Send the MAIL command to the server.
$smtp->mail("user\@sombody.com");
#Send the server the 'Mail To' address.
$smtp->to("user\@somewhere.com");
#Start the message.
$smtp->data();
#Send the message.
$smtp->datasend("Subject: Console test Post tcp update Very Very Cruel World!\n\n");
$smtp->datasend("\n\n");
$smtp->datasend("Good bye Cruel World!\n\n");
#End the message.
$smtp->dataend();
#Close the connection to your server.
$smtp->quit();

First of all thanks to everyone who has responded. I've run a few more test and the problem is clearly around "MOD_Perl". I've load an SMTP server on the same system where I'm running the apache server and the scripts fail to establish a session.
I'm able to run those scripts same scripts successfully from the console using the Netware Perl Interpreter. Both the Apache MOD_PERL and Netware NLM are 5.8.4 version of Perl. I'm running apache 2.0.59. on Netware 6.5 sp6.

Net::SMTP is known to work, though I'm not currently using it.
You could add
local $SIG{__WARN__} = \&Carp::cluck;
local $SIG{__DIE__} = \&Carp::confess;
This will help tell you where in Net::SMTP you are having a problem.
Once you know that, you can try to fix it.
OR this works --
use MIME::Lite ();
sub email {
my %args = @_;
my $email = MIME::Lite->new( Type => 'multipart/mixed' );
$email->add(To => $args{to});
$email->add(BCC => $args{bcc});
$email->add(From => $args{from});
$email->add(Subject => $args{subject});
$email->attach(Type => "TEXT", Data => $args{data});
MIME::Lite->send('smtp', SMTP_HOST, Timeout => 5);
eval { $email->send };
return $@;
}

Was I even alive when this version of mod_perl was out ?
Given that, more importantly, what version of perl are you using ?

Got it working after updating UPDATING TCPIP stack. I have noticed after I do a few operations or process a form with a fair amount of data I start getting this error :
Failed to open SMTP connection: Inappropriate I/O control operation
Could this be some sort of Buffer issue. Here is a small piece of test code I'm using to work on the problem :
#!/usr/bin/perl
use Net::SMTP;
#Create a new object with 'new'.
$smtp = Net::SMTP->new("10.102.10.74");
if ( ! $smtp ) {
die "Failed to open SMTP connection: ", $!, "\n";
}
#Send the MAIL command to the server.
$smtp->mail("user\@sombody.com");
#Send the server the 'Mail To' address.
$smtp->to("user\@somewhere.net");
#Start the message.
$smtp->data();
#Send the message.
$smtp->datasend("Subject: Console test Post tcp update Very Very Cruel World!\n\n");
$smtp->datasend("\n\n");
$smtp->datasend("Good bye Cruel World!\n\n");
#End the message.
$smtp->dataend();
#Close the connection to your server.
$smtp->quit();
