Re: newbie problem with Mail::POP3Client;

[Jim Maas]

Hi Wiggins,
It works!  Thanks a bunch.  I'm no computer newbie but am new to Perl, 
and where does one get started?  It was the AUTH_MODE, which had to be 
set to 'PASS'.  The machine it is connecting to is a Sun running Linux, 
but I don't know the flavour or what mailer.  This is just a 
demo/prototype but will try to upgrade this security in future.

I know the module installed the MAIL::POP3Client documentation when it 
installed but my bash just says
no such command as perldoc ...

Another challenge!
Thanks
Jim

Documentation for modules available on CPAN are always available online
in a quite readable format, for example,
http://search.cpan.org/~sdowd/Mail-POP3Client-2.16/POP3Client.pm
Also you can access most modules documentation after installation by
issuing,
perldoc 
perldoc Mail::POP3Client
 

By debug switch do you mean the optional debug_flag ?  No I haven't but 
about to.
   

Well yes, but it is 'DEBUG', and is passed to the constructor.
 

No idea what AUTH_MODE means, and my two oreilly perl books don't tell 
me either but I'll try and Google for it.

   

AUTH_MODE sets the mode that the POP client will use to send the
password. The POP3 server on the other end may or may not support
"encrypted" (actually hashed but that's another topic) passwords in
which case the AUTH_MODE may need to be set to tell the client to send
the password in clear text.  Setting AUTH_MODE to BEST seems to allow
the most flexibility. 

 

Thanks, have moved on a little!

No problem.

Did you turn on the DEBUG switch?  There is a section in the docs that
state that it will give an indication of errors. I copied your script,
turned it on, saw that the connection was successful by login was not. I
then attempted switching the AUTH_MODE for my connection to PASS (yes I
know what this means, do you? If not, learn before doing so.) and
everything then worked.

 

It runs, but I get "You have -1 messages"
  

   

The docs state that currently the only way to check for successful
connection is to ask for the number of messages, with -1 indicating
connection failure. I suspect 0 is success but empty, and >1 meaning
success and with messages.
Granted this is fairly annoying and I would think getting that switched
is high on their list.

 

I suspect the -1 means the variable has not been initialized or for
   

some 
 

reason it will not connect to the server.
  

   

-1 is initialization of the variable, just not a connection.

 

TIA
Jim

newbie problem with Mail::POP3Client;

[Jim Maas]

I'm sure you've seen this one hundreds of times!
I copied the following script, downloaded and installed the POP3Client 
module but it doesn't want to connect to an external POP3 server for me, 
for some reason.  I have put in the correct pop3 server, username and 
password, at least the same ones that work for me and will connect Mozilla.

Any thoughts about how to find the problem and/or debug?
It runs, but I get "You have -1 messages"
I suspect the -1 means the variable has not been initialized or for some 
reason it will not connect to the server.

TIA
Jim
#!/usr/bin/perl

use Mail::POP3Client;
my($pop, $num_mesg, $i);
$pop = new Mail::POP3Client( USER => "username",
   PASSWORD => "password",

$num_mesg = $pop->Count; #How many messages are there?
print ("You have ".$num_mesg." new messages.\n");
for ($i = 1; $i <= $num_mesg; $i++) {
