Hello,

since I live in a region where I have NO telephone line  which  mean  no
Internet too I am connecting to the internet over GSM/GPRS. But there is
a big problem:  I have several mail accounts and I am on  MANY  mailing-
lists...

Now, before downloading the messages I like to check from a small script
how many messages are in the Mailaccount and the size.  OK,  the  number
of mesages is no problem but the total size.

Querying an account with 3500 messages daily  cost  1700 kByte  GSM/GPRS
traffic which is realy expensive.

Now since I am beginner in perl, I like to  know,  whether  there  is  a
function to get the total size of a IMAP folder?

Note:  I use the Debian package "libnet-imap-simple-perl"
       if it is important for you to help.

My current script is:

----[ '~/bin/tdcheckimapsize' ]-----------------------------------------
#!/usr/bin/perl

use Net::IMAP::Simple;
use strict;
use Getopt::Long;

my $PASS="";
my $USER="[email protected]";
my $HOST="server4.pinguinhosting.de";

GetOptions('user=s'  => \$USER,
           'pass=s'  => \$PASS,
           'host=s'  => \$HOST);

die "No user given\n"     unless $USER;
die "No password given\n" unless $PASS;
die "No host given\n"     unless $HOST;

my $imap = Net::IMAP::Simple->new($HOST) || die
$Net::IMAP::Simple::errstr."\n";

unless($imap->login($USER, $PASS)){
	die "Login failed: " . $imap->errstr() . "\n";
}

my @mb=$imap->mailboxes;
my $size     = 0;
my $num_tot  = 0;
my $size_tot = 0;

foreach (@mb){
    my $num = $imap->select($_);
        for (my $i=1; $i <= $num; $i++){
            $size += $imap->list($i);
        }
    $num_tot  += $num;
    $size_tot += $size;
};

printf "%i %i", $num_tot, $size_tot/1024;

$imap->quit;
