in reply to Undef on POP3 method

It would appear that this line: 
$pop3 = Net::POP3->new('$host');

is failing. I would suspect the '$host' part. You are passing to new() a string containing $host, not the value of $host. Since $host is not specifically defined in your login() subroutine, it must be a global to have any value there.

I have not used POP3, but I suspect that $host is not what it expects. Try removing the single-quotes (which do not interpolate the value of any variables in them), or (yuck!) replacing them with double-quotes and see if it works correctly.

    Ahhah! it worked. Thanx a bundle. I guess I was thinkin' to hard. Well, either that or I don't know what I'm doing. ;)

      Quick and dirty explanation of interpolation for ya:

      
my $this = 'hello';
my $thisvar = 'goodbye';

# prints 'hello' of course
print $this;

# single quotes mean no interpolation occurs, prints '$this'
print '$this';

# double quotes invoke interpolation, prints 'hello'
print "$this";

# perl does 'greedy' interpolation (don't know if that's the
# right term) so this prints 'goodbye'
print "$thisvar";

# this makes it explicit that we only want $this, so this
# line prints 'hellovar'
print "${this}var";

      I'm sure the faq has a more detailed explanation that covers list interpolation as well...

      You're certainly welcome. We all fall victim to this kind of error. If you are old (currently interpreted by Russ as > 31), you could just call this a "mature moment." :-)

      Of course, by my metric, I will never get to say that about any of my sillinesses...

        Well actually I'm only 14... so I guess that's not old. I'll just consider this as a warning of things to come. ;)
