Re: PHP memory limit upper bound
Your posts are very hard to follow - perhaps Kmail is a little broken?
I've re-edited this post accordingly - though it still incorrectly shows
comment precedence.
Perhaps you are not simply selecting a response from the list and
choosing "reply to" as an option??

Did you restart the webserver after doing this? (any changes won't take
effect until after restarting the webserver)
e.g. # service apache2 restart

I'm not sure how file_put_contents would be affected by memory_limit
(and visa versa). max_input_time and max_execution_time might.

php.net ??
I included the link to the memory_limit documentation in a previous post.

Which means you have *no* memory limits set in php.ini
Try restarting the webserver - if that doesn't fix the problem then the
limit is being set by an application. .htaccess is the first place I'd
look, 2nd would be any application's config.php.
So, any limit is being set somewhere in your application, here's some
examples where that happened with a slightly earlier version of suhosin
patched php:-
