dovecot - Oct 2009 - Logging in with '+' delimiter

Dovecot v1.2.4
FreeBSD-7.2

I have Postfix configured to use Virtual Users & Domains and use
Dovecot for virtual delivery. Postfix also sends, dovecot correctly
places mail with '+'addressing; i.e., "foo+bar at domain.com"
into
"path-to-mail/domain.com/foo+bar". The problem is when I attempt to
access the mailbox, the user name: foo+bar at domain.com is rejected.

Is this by design, or is there a way to circumvent this problem?

Is this right? Typically it would be placed in mail/domain/foo/.bar/  
or something, i.e. a mailbox called" bar" for user "foo"..

You can safely add "+" to auth_username_chars setting.

If you are using plus addressing, the actual user is 'foo', so this mail
should go into '.../domain.com/foo', not '.../foo+bar' - unless
you are
using sieve, in which case it *could* be delivered to a subfolder called
'.../foo/.bar' or '.../foo.bar'

Thats because the user is 'foo', not 'foo+bar'...

If you are using dovecot LDA?
