correct gmail module?

CColin has asked for the wisdom of the Perl Monks concerning the following question:

Hi all I'm trying to solve what sounds like a simple problem: Find all unique email addresses in my google apps gmail account. However, have tried various gmail modules on the cpan without much success - and that's purely to download the corpus of messages. Once I have the corpus I'm more hopeful on parsing unique addresses. Before I start again from scratch, is there a well used gmail module that I am missing out there?

    Maybe you could tell us what you have tried?

    • Which specific CPAN modules did you try?
    • What specific problems did you see?
      • Did the modules download? Did they install?
      • Could you access them in your scripts? Are they on your include path? (if not, check the value of @INC)
      • If so, did the script connect to Google's website?
    • What specific error messages did you see at the point where things stopped working?
    • If you were able to install the module and use the module in your code, what does your code look like? Could you post a sample?
    • Finally, what communication protocols do the modules you've tried rely on? Are you sure your system's firewall is set up to allow outgoing and incoming messages using that protocol?

    Best, beth

    Considering that Gmail is an IMAP provider, I'd use whatever IMAP module is the best for your purposes, rather than trying to screen-scrape Gmail. I'll reply with a quickie Net-IMAP script that should point you in the right direction in just a bit.
      Try Mail-IMAPClient and IO::Socket::SSL instead (sorry about bad module choice earlier):
      use strict; use warnings; require IO::Socket::SSL; require Mail::IMAPClient; # Gmail does not provide a non-SSL IMAP server. my $socket = IO::Socket::SSL->new("imap.gmail.com:993") my $imap = Mail::IMAPClient->new( Server => 'imap.gmail.com' User => 'you@gmail_labs.com', Password=> $pass, Socket => $socket, ) or die "Cannot connect to $host as $id: $@"; my %address_list; my @messages = $imap->messages(); foreach my $message (@messages) { my $envelope = $imap->get_envelope($message); my $from = $envelope->from(); foreach my $from_address (@{$from}) { $address_list{$from_address} = 1; } my $to = $envelope->to(); foreach my $to_address (@{$to}) { $address_list{$to_address} = 1; } my $cc = $envelope->cc(); foreach my $cc_address (@{$cc}) { $address_list{$cc_address} = 1; } my $replyto = $envelope->replyto(); foreach my $replyto_address (@{$replyto}) { $address_list{$replyto_address} = 1; } my $sender = $envelope->sender(); foreach my $sender_address (@{$sender}) { $address_list{$cc_address} = 1; } } $imap->logout(); my @address_list = keys %address_list; ...

      Note that this will only catch message in the root IMAP folder ATM - although it can be easily extended. But then, does GMail have real "folders" as such?

        As I said, this was a quickie. It's $imap->to_addresses you'll need to use, rather than $imap->to, and so on. (the second returns parsed objects, the first returns e-mail addresses as strings)
        Thanks - looks nice; it was the modules with gmail in the name that I was having trouble with.
