IIRC, that's not two kernels - one is a dummy package. It means you can install
something like linux-2.6-amd64 and it'll get the most recent one (via a string
of dummies).

Maildir is faster under certain circumstances; mbox stores a whole mail folder
in one file, so has to read in the entire file to read or write to it. Maildir
doesn't, but if you're searching a lot it's slower, since it needs to open
every file individually. Or something along those lines.
Courier doesn't support anything but Maildir; most other MTAs and IMAP/POP3
servers support both (exim and postfix do, as does Dovecot). Solution: don't
use Courier.
