Why should a disabled LDA or a relayhost help in this matter? Honestly, who is 
sending what to where anyway? 

I mean Dovecot is an IMAP-Server: It receives emails from Postfix and 
mailclients connect to Dovecot to get these mails. When a mailclient sends an 
email it connects to Postfix not to Dovecot, so a delivery "within Dovecot" 
isn't really happening. Dovecot's LDA has options to send (bounce) mails back 
to Postfix. I guess loops occur there?

WHO doesn't know that abcd at localdomain.com is located on Dovecot -- Dovecot 
itself (= unknown recipient or perhaps permission problems while saving the 
mail) or Postfix (= no transport to Dovecot)?
