Finding incoming mail server by email address

hello,

I am a newbie :p I want a program to find the incoming mail server by entering an email address.

for example:

input: username@gmail.com
result: pop.gmail.com

please help! thanks

 

From the mail header itself we can see the incoming mail server

 

Using the Perl's Mail::Module you can get and set the email header informations.
For further informations please visit the perl's CPAN search about Mail::Header

 

thanks, can give me an example?

 

Here the sample code for extracting the header part from the mail.

Code:

use strict;
use warnings;
use Data::Dumper;

use Mail::Header;
my $messagefile = "mail"; #here the mail is a file which contains s data as this is for testing
open(MESSAGE,"$messagefile") or
die "Unable to open $messagefile:$!\n";
my $header = new Mail::Header \*MESSAGE;
print Dumper \$header;
close(MESSAGE);

The output will be as follows

Code:

$VAR1 = \bless( {
                   'mail_hdr_foldlen' => 79,
                   'mail_hdr_modify' => 0,
                   'mail_hdr_list' => [],
                   'mail_hdr_hash' => {},
                   'mail_hdr_mail_from' => 'KEEP',
                   'mail_hdr_lengths' => {}
                 }, 'Mail::Header' );
