NAME

Net::ValidMX - PERL Module to use DNS to verify if an email address could be valid.

SYNOPSIS

Net::ValidMX - What I wanted was the ability to use DNS to verify if an email address COULD be valid. This could be used for sender verification with programs such as MIMEDefang or for websites to verify email addresses prior to registering users and/or sending a confirmation email.

INSTALLATION

To install this package, uncompress the distribution, change to the directory where the files are present and type:

perl Makefile.PL
make
make install

USE

To use the module in your programs you will use the line:

use Net::ValidMX;

check_valid_mx

To check if an email address could be valid by checking the DNS, call the function check_valid_mx with the email address as the only argument:

&Net::validMX::check_valid_mx('kevin.mcgrail@thoughtworthy.com');

EXAMPLE

The distribution contains an example program suitable to demonstrate working functionality and to query one or more email addresses.

Without any parameters, it will run a set of default tests:

perl examples/check_primary_mx.pl

Otherwise, run the program with the email addresses to test as your arguments:

perl examples/check_primary_mx.pl kevin.mcgrail@thoughtworthy.com

CAVEATS

TODO

- I'd like to convert the example script into a test script.
- I'd like to make it so that the Makefile.PL creates a README on the fly from the pod in the library instead of pod2text lib/Net/validMX.pm > README.
