Actually, ispell should not be put here. mml-generate-mime will be
called more than once if there is "Gcc:" head or so.  Beside,
post-processing was called on the buffer containing generated mime,
therefore, the content could be some encoded text. You should still
use message-send-hook and find the certain part.

This is reasonable, but not an example for post-processing because of
the same reason stated above.  Anyway, I've added mml-tweak-type-alist
and mml-tweak-function-alist for this purpose. For example:

<#part type="text/plain" disposition=inline tweak=my-enrich-part>

and define a function my-enrich-part.  

This part of code is not tested. If you found bugs, please report them.
