POP3Client connection problems

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

Good day Monks. When running the following code (in which the parameters have been changed or replaced with * to protect the innocent):

use strict;
use Mail::POP3Client;
my $pop = new Mail::POP3Client( USER     => "uid",
                               PASSWORD => "pw",
                               HOST     => "mail.*****.com" );
print join("\n",@{ $pop->{'tranlog'} });
$pop->Close();

I get the following tranlog output and error message:

+OK <281**.1103124993@pop03.****.******.net>
APOP  uid   431b9d95123c88179f74489d3549f4**
-ERR authorization failed
CAPA
USER  uid

Use of uninitialized value in pattern match (m//) at C:/Perl/site/lib/
+Mail/POP3Client.pm line 1008, <GEN1> line 2.

When per suggestion of the FAQ I add AUTH_MODE => 'PASS' to the constructor, I get:

+OK <121**.1103125459@pop02.****.******.net> 
USER  uid 
+OK
PASS  pw
-ERR authorization failed

uid and pw are known good. Any ideas what I am doing wrong?

Many thanks in advance....

Steve

It's possible that the server is configured to only support a specific auth method such as CRAM-MD5. You may want to try using AUTH_MODE => 'BEST' instead of PASS, which will cycle through several auth methods and try each.	[reply]

I believe 'BEST' is the default, so that's what I got on the fist try. When it attempts the second method it throws the error shown at the end of the first output. Steve	[reply]

How about running a packet capture program such as Ethereal on a host while using a working client and watching the traffic to see what happens? Then compare that to what Mail::Pop3 is sending.	[reply]

I may be missing something here, but the perldocs for Mail::POP3Client says: `AUTH_MODE - pass 'APOP' to force APOP (MD5) authorization. (default is + 'BEST') #so you should use AUTH_MODE => 'APOP',` [download] I'm not really a human, but I play one on earth. flash japh	[reply] [d/l]
