 Here is the quick explanation of what is going on here: When maddy receives a
 message on port 25, it runs a set of checks, checks the recipients against
-'destination' blocks, runs what is specified in local_delivery_actions
-(that includes alias_file) and finally delivers the message to targets inside
+'destination' blocks, runs what is specified in local_modifiers
+(that includes replace_rcpt file) and finally delivers the message to targets inside
 the matching 'destination' blocks.
