Desired flow looks like:
Dovecot ---------------------> Postfix --> Relay Server -┐ Dovecot <-- LMTP/LDA <-- Postfix <---------------------┘
Top part of that flow works fine - a message will get to the relay server and it will be send back to the postfix for a local delivery but then it will start to loop back to the relay server instead hand over to LMTP/LDA.
For some reason Postfix doesn't know that abcd@localdomain.com is located on Dovecot and it will try to send it back to the relay server. I have the same problem explained here: https://serverfault.com/questions/1010325/postfix-via-relay-server-and-lmtp-...
Thanks for any help! ~Adam

Is there any way to disable Dovecot LDA? I want to always send email via postfix and relay server even it will be a local delivery within the Dovecot server
Thanks, Adam
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@localdomain.com is located on Dovecot -- Dovecot itself (= unknown recipient or perhaps permission problems while saving the mail) or Postfix (= no transport to Dovecot)?

This question really belongs on the 'postfix' forum. Have you read <http://www.postfix.org/DEBUG_README.html> or better still, <http://www.postfix.org/DEBUG_README.html#mail>. The "postfinger" tool is the best way.
