William,

If I remember correctly, cl-smtp doesn't always write a blank line 
before the boundary string between two attachments. You might not notice 
an error but then your smtp host has a bug because it recognizes a 
boundary string that is not preceded by a blank line. Of course during 
development and testing I used a 'bad' smtp host. My client's smtp host 
was coded correctly and produced corrupted attachments.

Another suggestion: usocket 0.5.5 (not on quicklisp but on its home site).
