Who's going to be receiving this mail and what mail reader will they
be using? For e-mail I receive, I prefer bzip2 + uuencode piped
into sendmail. In the general case you probably should use mime.
I used metasend etc. to check this out at some point but I'll defer
to more experienced listers on this.
You might consider, though, just sending people a URL and have them
download the binary through http. If you are doing volume, you're
better off avoiding virus checker/MS exchange/mail quota etc. issues
on the receiving side.
