I'm probably missing something simple, but right now I'm stumped. The program I'm writing gets some of its variables from a configuration file, via the following code: 
open(CONFIG, "$cfgfile") or die "Can't open configuration file: $!";

while (<CONFIG>) {
    if (/^#/ or /^\n$/) {
        next;
    } else {
        chomp;
        s/\s//g;
        (my $n, my $v) = split(/=/);
        $CFG{$n} = $v;
    }
}

close(CONFIG);

Everything seems to work fine there. However, one of the variables is the hostname of a pop3 server ($CFG{pop3_host}). If I call  Net::POP3->new($CFG{pop3_host}) the connection to the pop3 server times out. However, this does not happen if I simply define the pop3_host variable statically (i.e.  $CFG{pop3_host} = "hostname"). Egad, what the heck is going on?
