The
mydestination parameter specifies what domains this
machine will deliver locally, instead of forwarding to another
machine. The default is to receive mail for the machine itself.
See the
VIRTUAL_README file for how to configure Postfix for
hosted domains.
You can specify zero or more domain names, "/file/name" patterns
and/or "
type:table" lookup tables (such as hash:, btree:, nis:,
ldap:,
or
mysql:), separated by whitespace and/or commas. A "/file/name"
pattern is replaced by its contents; "
type:table" requests that a
table lookup is done and merely tests for existence: the lookup
result is ignored.
IMPORTANT: If your machine is a mail server for its entire
domain, you must list $
mydomain as well.
Example 1: default setting.
/etc/postfix/main.cf:
mydestination = $
myhostname localhost.$
mydomain localhost
Example 2: domain-wide mail server.
/etc/postfix/main.cf:
mydestination = $
myhostname localhost.$
mydomain localhost $
mydomain
Example 3: host with multiple DNS A records.
/etc/postfix/main.cf:
mydestination = $
myhostname localhost.$
mydomain localhost
www.$
mydomain ftp.$
mydomain
Caution: in order to avoid mail delivery loops, you must list all
hostnames of the machine, including $
myhostname, and localhost.$
mydomain.
