I don't have any experience with Mail, but what exact process did you do for the install? ppm? cpan? make install? And what operating system are you on? Windows? Nix? Be more specific, and the monks will have a better idea of what could have gone wrong.
cheers for the reply.
Its all sorted now tho :D
i was using : perl -MCPAN -e 'install Mail::Box::POP3'
but ended up getting the tarball and doing a : perl Makefile.pl && make && make install
it seems to work fine now.
