I'm using Courier-imap and gonna change to dovecot. Courier-imap supports quota over 2GB size. Does dovecot's Maildir++ quota support over 2GB?

Yes, we are enforcing a 5GB per user quota using Dovecot's maildir++
quota support. This works with both 32-bit kernels and 64-bit. I
know courier took some patching to make work with 32-bit kernels,
but Dovecot supports it out of the box.

The only caveat is the quota is only enforceable within one
namespace, so make sure your Inbox and folders all use the same
namespace.

Thank you!
