How to set up and configure the Net::SMTP module in Perl?

To set up and configure the Net::SMTP module in Perl, follow these steps:

1. First, make sure you have the Net::SMTP module installed on your system. You can install it using the CPAN module by running the following command in your terminal:

1

perl -MCPAN -e 'install Net::SMTP'

1. Next, in your Perl script, you need to include the Net::SMTP module by adding the following line at the beginning of your script:

1

use Net::SMTP;

1. To create a new SMTP object, use the following code:

1

my $smtp = Net::SMTP->new('smtp.example.com', Timeout => 30) or die "Error creating SMTP object: $!";

Replace 'smtp.example.com' with the SMTP server address you want to connect to.

1. To authenticate with the SMTP server, use the following code:

1

$smtp->auth('username', 'password') or die "Authentication failed: $!";

Replace 'username' and 'password' with your SMTP server credentials.

$smtp->datasend("This is a test email sent from Perl using Net::SMTP.");
$smtp->dataend();
$smtp->quit;

Replace 'from@example.com' and 'to@example.com' with the sender and recipient email addresses, respectively.
