I have changed that in php I just wanted to make sure OsTicket would accept that as its' drop down menu only has 2MB max.Also I have searched "max file size" and "max attachment size" 3 pages down I still haven't found anything about increasing attachment size, it's more upgrading osticket related or imap related.Maybe there could be a Q/A section with common asked questions on the forum I wouldn't mind helping filling in some stuff also if you do decide to do this.
