this is a problem with the NCSA server - it truncates MIME headers to
MAX_STRING_LEN which defaults to 256. This is defined in httpd.h
Quick ugly hack to make it work - up the value of MAX_STRING_LEN. Real
solution: make ncsa httpd able to handle real RFC822 headers (arbitrary
length, multi-line, etc).
