Disable Dovecot LDA

[Adam Raszkiewicz]

So there is no way to skip Postfix for incoming messages and go directly to LMTP/LDA but I need two instances of Postfix in that case?

Regarding your second question - it is required to be complaint with Direct Trust. 

Thanks,
Adam

    This mail flow cannot work with one Postfix instance. Either Postfix
    knows that "localdomain.com" is local and should be delivered to the
    LDA, in which case it won't be forwarded to the relay server, or Postfix
    does not know that "localdomain.com" is a local address and therefor
    forwards it the relay server, but than it will do that anytime it sees
    "localdomain.com".
    
    Only possibility is to run two instances of Postfix.
    
    The real question is:
    Why do you want this mail flow? Where is the benefit in sending a local
    mail out to a relay server only to get it back and deliver it?
