decryption

[Pierre van Rooyen]

Will you please try to decrypt the following, I want to make sure it is not
decryptable.

Tips:
- Only a..z and A..Z is changed
- numbers,commas,spaces,ect. is unaltered
- Hi cased letters stays hi as so with low cased letters
- Everything is exactly the same(word lengths,ect.) only the letters of the
text   changed. 
- I don't want to explain how the text is encrypted because I want to keep it
  secret but I promise you that even if the source code of the program that
  decrypt/encrypt this text is supplied, it won't help you much
- The first paragraph decrypted reads:

There are plenty of programs you could buy such as 
Floodgate to pull your own addresses however, these 
programs (even when used properly) can take up to 6 months
just to pull as many as 750,000 addresses!  And after 
THAT time has elapsed you're database will have plenty
of addresses that are undeliverable.
