Hi! I had the chance to work with Roundcube only recently. I "inherited" this webmail setup from the previous admin and I have a very unsettling feeling that it wasn't set up properly, but it works. Due to the fact I want to upgrade it (it's out dated version 0.1) I took a closer look to it and discovered (because I want to make a new install and only import the data from the database tables into the new tables and drop the old installation entirely) that it uses InnoDB. My question is (pretty stupid question I know) will I break the program if I try to force it to use MyISAM engine instead of InnoDB, the reason being that InnoDB uses a lot of memory even when is in idle and the machine on which the webmail is hosted has very limited resources. Thank you!
