Check well formatted email address

Question

I have a text file of e-mails like this:

10:info@example.com;dev@example.com
12:john@host.com; "George <g.top@host.com>" 
43:jim.p@web.com.;sue-allen@web.com
...

I want to check whether the list contains well formatted entries. Do you know any tool or web-service to check and give me a list of invalid addresses?

Update Dear all, thank you for your input. I was really looking for a basic syntax check, so I will stay with Rafe's idea (I will do it with Java).

Answer 1

I wrote a simple Perl script that uses the Email::Address module to validate these addresses:

#!/usr/bin/env perl

use Email::Address;

while (<>) {
    chomp;
    @addresses = split /\;/;

    foreach my $address (@addresses) {
        if (!Email::Address->parse($address)) {
            print $address, "\n";
        }
    }
}

You'll just need to install the module. Its home page is:
