Re: emailpull.pl

my $fh = IO::File->new($MAILBOX)
  or die "unable to read mailbox '$MAILBOX': $!";
my $mail;
{
  local $/;
  $mail = <$fh>;
}
[download]

is probably better written as

my $mail = do
{
  my $fh = IO::File->new($MAILBOX)
    or die "unable to read mailbox '$MAILBOX': $!";
  local $/;
  <$fh>
};
[download]

That way, $fh gets automatically closed as soon as you're done reading it, and you declare and assign $mail in one step.

Also, if it was me, I'd probably sort the email addresses when printing them.
