Input Postfix config is generated for domains with inactive mail service

[TimReeves]

In master.cf I'm seeing lines for all domains - including simple forwarding domains with mail service deactivated. Unless I'm missing soemthing, this is just a waste of resources. For example:

plesk-tagesenergie.com-95.217.194.197-2a01-4f9-4a-51ed--2 unix - - n - - smtp -o smtp_bind_address=95.217.194.197 -o smtp_bind_address6=2a01:4f9:4a:51ed::2 -o smtp_address_preference=ipv4 -o smtp_helo_name=tagesenergie.com

whereby tagesenrgie.com is a simple forward to tagesenergie.org, and the mail serice is not activated.
