[imp] Patch for mbox downloads in IMP 3.2.5

[Chuck Hagenbuch]

Quoting Ross Becker <ross at rbecker.org>:

> I've patched IMP 3.2.5 to use a tmpfile() stream for generating mboxes

> the end and uses ftell() to find the size of the stream, and then does
> 8k blocks to deliver this to the user. This prevents large mail folders
> from blowing up PHP's memory size. I've generated a unified diff of my

It'd be best if it was against CVS HEAD, but it's an interesting idea. 
I've been
looking at Zend Download Server as well; I may write a class for 
wrapping either
this behavior or ZDS.

Btw, any reason you didn't use fpassthru()?
