You'd need an additional lmtp transport in master.cf with customized settings for lmtp_bind_address/lmtp_bind_address6 and myhostname (using the -o to set options), to which you would specifically direct email for that domain by setting up a transport table entry.
That would take care of half of the problem because now instead of "Received: from smtp.mydomain01.com" "by smtp.mydomain01.com (Dovecot) with LMTP id jMydI//Z3VUIOAAACRxwyw" You would get Received: from smtp.mydomain02.com ([ip address of smtp.mydomain02.com]) "by smtp.mydomain01.com (Dovecot) with LMTP id jMydI//Z3VUIOAAACRxwyw" To do the second part, I think you would need to use multiple dovecot instances or change the source code. As far as I know the dovecot hostname setting is one per instance either set manually or taken from the server hostname. best regards, John
