As I said, 8-bit can cause problems for some mail software.  What 
happens is that the 8th bit get stripped off (replaced with 0) which 
leaves the recipient with a useless text file of gibberish.  So, I 
usually play it safe and use MIME even thought it makes the attachment a 
little longer (7 bites are converted to 8 bites).

Sending a test to yourself is a good idea.  Try both 8-bit and MIME and 
confirm that they both work.
