Great Microsoft Outlook .MSG files converter

Just get these goodies in CPAN (Comprehensive Perl Archive Network):

perl -MCPAN -e 'install("Email::Outlook::Message")'
perl -MCPAN -e 'install("Email::LocalDelivery")'
perl -MCPAN -e 'install("Getopt::Long")'
perl -MCPAN -e 'install("Pod::Usage")'
perl -MCPAN -e 'install("File::Basename")'

And then, go to http://www.matijs.net/software/msgconv/ and download the Perl script msgconvert.pl (see the link "script itself" near the bottom of the above-mentioned Web page).
Use it like this:

perl -w ~/msgconvert.pl ~/your_message.msg

And your_messagemsg..mime is generated. Now open it with your favorate mail client and we are set!
