From a Perl script running on a Windows 2003 Server, I need to monitor a folder for the arrival of certain files and email those files as attachments to another party. I also need the ability to specify a Reply-To address that is different from the Sender address. I see a multitude of mail related modules that are available when I put "mail" in the filter of ActiveState's Perl Package Manager. Which one would you recommend for the simplest implementation? I don't need any whistles or bells other than what I mentioned above. I am using ActiveState's Perl v5.8.8 built for MSWin32-x86-multi-thread, binary build 820.
