No one is saying it is, but then don't use code (regardless if it's 
yours or not) that causes that causes DoS or at least add a warning to 
that effect in the config files.

But it's not a bug in our code.

Well, this is kind of a bug, and a major one - if you're using 
something that causes a DoS if enabled, you should at least add a 
warning or something? -- Every time someone opens a larger uuencoded 
email/file (say >3MB), horde as a hole (i.e. for other users) becomes 
unavailable for up to a minute or 2 on powerful hardware (AMD Athlon64 
FX60) - that's bad.

Unless you're willing to do some work here, you're probably out of 
luck. We use PEAR's Mail_mimeDecode to handle uudecoding. You might be 
better off bugging them to improve performance.

I've enabled uuencode support:



mime_drivers.php:$mime_drivers['imp']['plain']['uuencode'] = true;



And now I can view uuencoded files, but small ones (under 1MB) take 
5-30 seconds to show freezing up the webserver, and larger ones 
(tested with 3MB) just show the file as plaintext on the screen.



Would be nice if the uudecoding was sped up as in it's current state 
users are causing DoS whenever they recieve a uuencoded email.
