I must say I haven toyed with this for a long time.

Well, clearly LDA is using a bare username and not username at domain.tld. 
Now I am interested in how dovecot-lda is called from your MTA (e.g. 
from Exim/Postfix/Qmail). Particularly these arguments are interesting 
(http://wiki2.dovecot.org/LDA):

-d <username>: Destination username. If given, the user information is 
looked up from dovecot-auth. Typically used with virtual users, but not 
necessarily with system users. -a <address>: Destination address (e.g. 
user+ext at domain). Default is the same as username.

Also take a look at the MTA-specific pages referenced from the LDA wiki 
page for examples.

Regards,

Stephan.
