I received the maximum upload of 2m exceeded error and googled it and it landed me here.
Maybe I missed something - but I made the standard changes to the vanilla install for config files, and the error went away...
a) edited /etc/httpd/conf.d/roundcube.conf
...
php_value upload_max_filesize 12M #default is 2M
...
b) edited /etc/php.ini
...
; Maximum size of POST data that PHP will accept.
post_max_size = 12M #default is 8M
...
; Maximum allowed size for uploaded files.
upload_max_filesize = 12M #default is 2M
Running
centOS 5.1 x86_64
apache2, php 5, mysql etc.
I don't think this plays into this - but I am using imapproxy for roundcube - which makes the application a lot more "peppy."

As far as "spiraling out of control..." - is there a measurable threshold? Like say 8-12M or something? As up to 3MB its been smooth sailing for me so far. I'll try some larger files - I wonder if postfix/sendmail MTAs have anything to do with the stability of the product?
Food for thought.
