Mail::Verify - Utility to verify an email address
"Mail::Verify" provides a function
CheckAddress function for verifying email addresses. First the syntax of the
email address is checked, then it verifies that there is at least one valid MX
server accepting email for the domain. Using Net::DNS and IO::Socket a list of
MX records (or, falling back on a hosts A record) are checked to make sure at
least one SMTP server is accepting connections.
Here are a list of return codes and what they mean:
- 0
- The email address appears to be valid.
- 1
- No email address was supplied.
- 2
- There is a syntaxical error in the email address.
- 3
- There are no DNS entries for the host in question (no MX records or A
records).
- 4
- There are no live SMTP servers accepting connections for this email
address.
This example shows obtaining an email address from a form field and verifying
it.
use CGI qw/:standard/;
use Mail::Verify;
my $q = new CGI;
[...]
my $email = $q->param("emailaddr");
my $email_ck = Mail::Verify::CheckAddress( $email );
if( $email_ck ) {
print '<h1>Form input error: Invalid email address.</h1>';
}
[...]
