For sending emails with attachments, under Win32 I often use blat from http://www.blat.net/. It is rather comfortable and somewhere (CPAN?) also exists a Perl-Interface (which I've never used yet). The only problem is the following: It doesn't run under Non-Win32-Systems...

Best regards,
perl -le "s==*F=e=>y~\*martinF~stronat~=>s~[^\w]~~g=>chop,print"
