generic – Postfix generic table format

It has been taken from man – an interface to the on-line reference manuals.

The following shows a generic mapping with an indexed file. When mail
is sent to a remote host via SMTP, this replaces his@localdomain.local
by his ISP mail address, replaces her@localdomain.local by her ISP mail
address, and replaces other local addresses by his ISP account, with an
address extension of +local (this example assumes that the ISP supports
“+” style address extensions).

/etc/postfix/main.cf:
smtp_generic_maps = hash:/etc/postfix/generic

/etc/postfix/generic:
his@localdomain.local hisaccount@hisisp.example
her@localdomain.local heraccount@herisp.example
@localdomain.local hisaccount+local@hisisp.example

Execute the command “postmap /etc/postfix/generic” whenever the table
is changed. Instead of hash, some systems use dbm database files. To
find out what tables your system supports use the command “postconf -m”.

HISTORY
A genericstable feature appears in the Sendmail MTA.
This feature is available in Postfix 2.2 and later.
