unixhierarchysep is your answer for the mailbox question. Enable that and then 
do:

createmailbox user/jay at jay.fm

As far as sasl, it usually sets the default realm to the hostname of the 
machine it's running on. So jay at jay.fm probably get's authenticated as 
jay at jay.fm@linux.home.jay.fm

So when you create the user in sasldb:

saslpasswd2 -c jay at jay.fm 

and it will fill in the realm with @linux.home.jay.fm. If cyrus is running on 
the same machine, it should default the realm to be @linux.home.jay.fm as 
well.

sasldblistusers2 should give you something like:

jay at jay.fm@linux.home.jay.fm: userPassword
jay at jay.fm: cmusaslsecretOTP

HTH,
