attach zip file to email in 4.6C

Hi!

I'm trying to attach a zip file to an email. I'm using 4.6C. I dont have cl_document_bcs or cl_abap_zip in our server. My questions are:

*Is there a patch that we can add so we can have those class?

*Is there any other way or maybe a function module that we can use to attach a zip file?

Thanks!
