Alias and address MTA options

This discussion will focus on those MTA options that affect and modify certain fundamental aspects of MTA alias and address handling, and in particular  those MTA options  affecting MTA alias file  or alias database handling.

For options relating more specifically to mail group or mail list handling, (as note that groups and lists are merely special forms of alias), see also Mailing list and group MTA options.

And for the (many, many) options relating more specifically to aliases stored in LDAP -- the so-called "Direct LDAP" MTA options -- see also Direct LDAP MTA options.
