There are two factors at play here: MTA settings and PHP settings.

MTA: Go to "Network Services" / "Email" and in the "Advanced" tab check 
what you have set for "Maximum Email Size (MB)". It may be empty, in 
which case there is no limit for max email size. If it is empty, you can 
leave it as it is. Otherwise set whatever size you see fit.

PHP Settings: Each RoundCube install uses whatever PHP settings the 
Vsite has configured. So if a RoundCube install says that your 
attachment size is limited to 2MB, then check the PHP settings of that 
Vsite in question. See what values are configured for "Upload max 
filesize" and "Post max size" and adjust them accordingly.
