Are you using ActiveState Perl on the windows machines ?
1) Win32::FileSecurity;

3) You need a mail server (SMTP/POP) accessible on your network

which module cotains



First of all, I recommend using ActiveState perl for windows environment. (www.activestate.com)

To install Win32::FileSecurity you can do this with PPM (Perl Package Manager):

PPM> install Win32-FileSecurity
Install package 'Win32-FileSecurity?' (y/N): y
....'Retrieving package 'Win32-FileSecurity
Installing C:\Perl522\site\lib\auto\Win32\FileSecurity\FileSecurity.dll
Installing C:\Perl522\site\lib\auto\Win32\FileSecurity\FileSecurity.exp
Installing C:\Perl522\site\lib\auto\Win32\FileSecurity\FileSecurity.lib
Installing C:\Perl522\html\lib\Win32\FileSecurity.html
Installing C:\Perl522\htmlhelp\pkg-Win32-FileSecurity.chm
Installing C:\Perl522\htmlhelp\pkg-Win32-FileSecurity.hhc
Installing C:\Perl522\site\lib\Win32\FileSecurity.pm
Writing C:\Perl522\site\lib\auto\Win32\FileSecurity\.packlist

You can see which packages are available for ActiveState perl in:


To deal with mail issues, you can do

PPM> install MailTools

Then check the ActivePerl->OnlineDocumentation

You will see lots of new mail stuff like:


> 2) Is there a sendmail program for windows ?

There is a program called "blat" for windows I know of, but when I tried using it , it crashed in several circumstances.

What works best is using Mail::Sender.pm, as discussed in:


If you would like to work with it, tell me and I will post more info on this, as configuring this could be somewhat tricky.

When you install ActiveState Perl, the online documentation installed contains the following FAQs, dealing with programming perl on windows platforms.  

    perlwin32faq: Overview of the Win32 Perl FAQ (this document) (Updated: 3/3/99)
    perlwin32faq1: Availability and Installation
    perlwin32faq2: PerlIS
    perlwin32faq3: Documentation and Support
    perlwin32faq4: Windows NT and Windows 95 (Updated: 3/11/99)
    perlwin32faq5: Implementation Quirks
    perlwin32faq6: Web Server Configuration and Troubleshooting
    perlwin32faq7: Web Programming (CGI and PerlIS)
    perlwin32faq8: General programming
    perlwin32faq9: Modules/sample scripts (Updated: 3/11/99)
    perlwin32faq10: Embedding and Extending
    perlwin32faq11: Using PPM to install modules (Updated: 3/3/99)
    perlwin32faq12: Using OLE with Perl  (Updated: 3/11/99)

Note that there are all sorts of quirks in the windows95 implementation.

Also note that I have not worked with win98, and all the info I am commenting is tested on WinNT plaform.

You can make the linux machine a mail server for itself and the other 2 windows machines on the network.

To get the linux machine to be your mail-server, it needs to handle
the protocols SMTP POP3 IMAP.

My platform is redhat-linux 5.1, so the info below may be specific
to redhat linux.

Redhat linux installation contains support for these protocols,
so there is no need for you to get 3rd party software.

You can do telnet to the linux box to ports 25 - STMP, 110 - POP3
and see what answer you are getting.

You can try configuring OUTLOOK / OUTLOOK express against the
linux box which can serve as an SMTP/POP3 server.

The mail accounts are someuser@linuxbox (unix users on the linux box),
to which you can connect from outlook / outlook express, or your own
custom mail client software running on the windows machines
(written in perl for example).

If you are having trouble, try looking at
on the linux box.

You can also use
   /usr/sbin/tcpdump port 110  
   /usr/sbin/tcpdump port 25

To see network traffic on specific ports of your linux box.

If you have redhat 6.1, look at


(search for POP3 on this page)


BTW- How are you getting along ?

Do you know of any web based admin script ?

For adding pop3 users ?

For adding system users etc ?

email  me at christopher_sagx@yahoo.com
You could write a perl-CGI that would accept input and call the linux command "adduser" to create new unix users.
 Once a unix user is added, he will be able to receive mail.
 I am assuming you don't need this to be highly secure.
