## The internet domain name of this mail system. The default is to use $myhostname minus the first component
# mydomain = putin.ru

## The internet hostname of this mail system. The default is to use the fully-qualified domain name (FQDN) from gethostname(), or to use the non-FQDN result from gethostname() and append ".$mydomain". $myhostname is used as a default value for many other configuration parameters.
myhostname = mail.putin.ru

##  The domain name that locally-posted mail appears to come from, and that locally posted mail is delivered to. The default, $myhostname, is adequate for small sites. If you run a domain with multiple machines, you should (1) change this to $mydomain and (2) set up a domain-wide alias database that aliases each user to [email protected].
# myorigin = /etc/mailname
myorigin = putin.ru

## (default: $myhostname, localhost.$mydomain, localhost)
## The list of domains that are delivered via the $local_transport mail delivery transport.
## The default mydestination value specifies names for the local machine only. On a mail domain gateway, you should also include $mydomain.
