# INTERNET HOST AND DOMAIN NAMES
# 
# The myhostname parameter specifies the internet hostname of this
# mail system. The default is to use the fully-qualified domain name
# from gethostname(). $myhostname is used as a default value for many
# other configuration parameters.
#
#myhostname = host.domain.tld
myhostname = myservername.mydomainname.com

# The mydomain parameter specifies the local internet domain name.
# The default is to use $myhostname minus the first component.
# $mydomain is used as a default value for many other configuration
# parameters.
#
mydomain = mydomainname.com

# ALIAS DATABASE
#
# The alias_maps parameter specifies the list of alias databases used
# by the local delivery agent. The default list is system dependent.
#
# On systems with NIS, the default is to search the local alias
# database, then the NIS alias database. See aliases(5) for syntax
# details.
# 
# If you change the alias database, run "postalias /etc/aliases" (or
# wherever your system stores the mail alias file), or simply run
# "newaliases" to build the necessary DBM or DB file.
#
# It will take a minute or so before changes become visible.  Use
# "postfix reload" to eliminate the delay.
#
#alias_maps = dbm:/etc/aliases
alias_maps = hash:/etc/aliases
#alias_maps = hash:/etc/aliases, nis:mail.aliases
#alias_maps = netinfo:/aliases

# The alias_database parameter specifies the alias database(s) that
# are built with "newaliases" or "sendmail -bi".  This is a separate
# configuration parameter, because alias_maps (see above) may specify
# tables that are not necessarily all under control by Postfix.
#
#alias_database = dbm:/etc/aliases
#alias_database = dbm:/etc/mail/aliases
alias_database = hash:/etc/aliases
#alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases

# CANONICAL MAPPING
#
# (from example in /etc/postfix/samples, added by Red 6/28/06
# The canonical_maps parameter specifies optional address mapping
# lookup tables. The mapping is applied to both sender and recipient
# addresses, in both envelopes and in headers. This is typically used
# to clean up dirty addresses from legacy mail systems, or to replace
# login names by Firstname.Lastname. See canonical(5) for details.
# 
# By default, no canonical address mapping is done.
#
# If you use this feature, run "postmap /etc/postfix/canonical" to
# build the necessary DBM or DB file after every change. The changes
# will become visible after a minute or so.  Use "postfix reload"
# to eliminate the delay.
#
canonical_maps = hash:/etc/canonical

#        sender_canonical_maps
#               Address  mapping  lookup  table  for  envelope  and
#               header sender addresses.
