Yes, but 'deliver' does not itself make those decisions. If you want 
mail delivered anywhere other than INBOX, you need to either call 
deliver with a -m argument or use a plugin (e.g. sieve) and as far as 
I can tell, only the sieve plugin can set IMAP message flags on 
delivery. As for 'virtual labels,' I assume you are referring to 
TBird's 'Tags' which map loosely to IMAP custom message flags, 
(a.k.a. keywords.) The looseness is that TBird seems to ignore 
keywords that it has not been explicitly configured to show, so if 
sieve does add a keyword to a message, it has to be one known to 
TBird in order to be used by TBird.

There has to be user-specific and MUA-specific configuration for the 
usage model you seem to want. There really isn't much more that a 
LDA/IMAP combination can do to support a GMail-like presentation, 
that has to be done by the MUA, i.e TBird.
