'yes' : 'no');</code></pre> <h1 id="DESCRIPTION">DESCRIPTION</h1> <p>This module determines whether an email address is well-formed, and optionally, whether a mail host exists for the domain.</p> <p>Please note that there is no way to determine whether an address is deliverable without attempting delivery (for details, see <a href="http://perldoc.perl.org/perlfaq9.html#How-do-I-check-a-valid-mail-address">perlfaq 9</a>).</p> <h1 id="PERL-VERSION"><a id="PERL"></a>PERL VERSION</h1> <p>This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years.</p> <p>Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.</p> <h1 id="PREREQUISITES">PREREQUISITES</h1> <p>This module requires perl 5.004 or later and the <a href="/pod/Mail::Address">Mail::Address</a> module. Either the <a href="/pod/Net::DNS">Net::DNS</a> module or the nslookup utility is required for DNS checks. The <a href="/pod/Net::Domain::TLD">Net::Domain::TLD</a> module is required to check the validity of top level domains.</p> <h1 id="METHODS">METHODS</h1> <p>Every method which accepts an <code><ADDRESS></code> parameter may be passed either a string or an instance of the Mail::Address class. All errors raise an exception.</p> <dl> <dt id="new-(-[PARAMS]-)"><a id="new"></a><a id="new-PARAMS"></a>new ( [PARAMS] )</dt> <dd> <p>This method is used to construct an Email::Valid object. It accepts an optional list of named parameters to control the behavior of the object at instantiation.</p> <p>The following named parameters are allowed. See the individual methods below for details.</p> <pre><code>-mxcheck -tldcheck -fudge -fqdn -allow_ip -local_rules</code></pre> </dd> <dt id="mx-(-<ADDRESS>|<DOMAIN>-)"><a id="mx"></a><a id="mx-ADDRESS-DOMAIN"></a>mx ( <ADDRESS>|<DOMAIN> )</dt> <dd> <p>This method accepts an email address or domain name and determines whether a DNS record (A or MX) exists for it.</p> <p>The method returns true if a record is found and undef if not.</p> <p>Either the Net::DNS module or the nslookup utility is required for DNS checks. Using Net::DNS is the preferred method since error handling is improved. If Net::DNS is available, you can modify the behavior of the resolver (e.g. change the default tcp_timeout value) by manipulating the global <a href="/pod/Net::DNS::Resolver">Net::DNS::Resolver</a> instance stored in <code>$Email::Valid::Resolver</code>.</p> </dd> <dt id="rfc822-(-<ADDRESS>-)"><a id="rfc822"></a><a id="rfc822-ADDRESS"></a>rfc822 ( <ADDRESS> )</dt> <dd> <p>This method determines whether an address conforms to the RFC822 specification (except for nested comments).

That means addresses like: <code>rjbs@[1.2.3.4]</code></p> <p>The checking for the domain literal is stricter than the RFC and looser than checking for a valid IP address, <i>but this is subject to change</i>.</p> <p>The default is true.</p> </dd> <dt id="fqdn-(-<TRUE>|<FALSE>-)"><a id="fqdn"></a><a id="fqdn-TRUE-FALSE"></a>fqdn ( <TRUE>|<FALSE> )</dt> <dd> <p>Specifies whether addresses passed to address() must contain a fully qualified domain name (FQDN). The default is true.</p> <p><b>Please note!</b> FQDN checks only occur for non-domain-literals. In other words, if you have set <code>allow_ip</code> and the address ends in a bracketed IP address, the FQDN check will not occur.</p> </dd> <dt id="tld-(-<ADDRESS>-)"><a id="tld"></a><a id="tld-ADDRESS"></a>tld ( <ADDRESS> )</dt> <dd> <p>This method determines whether the domain part of an address is in a recognized top-level domain.</p> <p><b>Please note!</b> TLD checks only occur for non-domain-literals.

Otherwise, undef is returned. In a list context, the method also returns an instance of the Mail::Address class representing the email address.</p> </dd> <dt id="details-()"><a id="details"></a>details ()</dt> <dd> <p>If the last call to address() returned undef, you can call this method to determine why it failed. Possible values are:</p> <pre><code>rfc822 localpart local_rules fqdn mxcheck tldcheck</code></pre> <p>If the class is not instantiated, you can get the same information from the global <code>$Email::Valid::Details</code>.</p> </dd> </dl> <h1 id="EXAMPLES">EXAMPLES</h1> <p>Let's see if the address 'maurice@hevanet.com' conforms to the RFC822 specification:</p> <pre><code>print (Email::Valid->address('maurice@hevanet.com') ? 'yes' : 'no');</code></pre> <p>Additionally, let's make sure there's a mail host for it:</p> <pre><code>print (Email::Valid->address( -address => 'maurice@hevanet.com', -mxcheck => 1 ) ? 'yes' : 'no');</code></pre> <p>Let's see an example of how the address may be modified:</p> <pre><code>$addr = Email::Valid->address('Alfred Neuman <Neuman @ foo.bar>'); print "$addr\n"; # prints Neuman@foo.bar</code></pre> <p>Now let's add the check for top level domains:</p> <pre><code>$addr = Email::Valid->address( -address => 'Neuman@foo.bar', -tldcheck => 1 ); print "$addr\n"; # doesn't print anything</code></pre> <p>Need to determine why an address failed?</p> <pre><code>unless(Email::Valid->address('maurice@hevanet')) { print "address failed $Email::Valid::Details check.\n"; }</code></pre> <p>If an error is encountered, an exception is raised. This is really only possible when performing DNS queries. Trap any exceptions by wrapping the call in an eval block:</p> <pre><code>eval { $addr = Email::Valid->address( -address => 'maurice@hevanet.com', -mxcheck => 1 ); }; warn "an error was encountered: $@" if $@;</code></pre> <h1 id="CREDITS">CREDITS</h1> <p>Significant portions of this module are based on the ckaddr program written by Tom Christiansen and the RFC822 address pattern developed by Jeffrey Friedl.
