Hello-

I am trying to run a script that logs into a pop3 server multiple times using a text file with usernames and passwords. The purpose of this is to migrate user accounts from an IMAIL server to a MailEnable server via an IMAP connector.

urgoll has provided the script below, but when it is run I get an error that says:
Bad file descriptor at script.txt line 24, <FILE> line 2

C:\>perl script.txt input.txt
Processing user philip1 with password password1
   Account has 27 messages.
Processing user philip2 with password password2
Could not log in: Bad file descriptor at script.txt line 24, <FILE> line 2.

I have just installed the most recent version of ActivePerl on WIndows XP.

The input file looks like this:

philip1 password1
philip2 password2
philip3 password3
...

Any thoughts on how to resolve this issue?

THank you,
#!/usr/bin/perl
 
use strict;
use Net::POP3;
 
# Replace following line with the actual server name for the POP3 service
my $servername = 'rt.accovia.com';
 
my $filename = shift;
if (!$filename || $filename eq '') { 
	print "Usage: script.pl <inputfilename>\n",
	      "   where <inputfilename> is a text file with username and passwords for the POP accounts.\n\n";
	exit(1);
}
 
 
my $pop = Net::POP3->new($servername, Timeout => 120);	# define server with 2 minutes timeout
 
open (FILE,$filename) or die "Cannot open input file";
 
while (<FILE>) {
	if ($_ =~ /^\s*(\S+)\s+(\S+).*/ ) {
		print "Processing user ",$1," with password ",$2,"\n";
		$pop->login($1,$2) or die "Could not log in: $!";
		my $msgnums = $pop->list or die "Could not get msg list: $!";
		my $cnt = keys %$msgnums || 0;
		print "   Account has $cnt messages.\n";
		$pop->reset();
		$pop->quit();
	} else {
		print "Line didn't match expected values:\n";
		print $_;
	}
}
close(FILE);
print "Done processing input file\n";

Try turning debugging on.
Usually that error happens when the socket was closed.

Try:
my $pop = Net::POP3->new($servername, Timeout => 120, Debug=> 1);
