-# Mail Server configuration
-# -------------------------
-
-# Please select the mail server configuration type that best meets your needs.
-
-# Systems with dynamic IP addresses, including dialup systems, should generally be
-# configured to send outgoing mail to another machine, called a 'smarthost' for
-# delivery because many receiving systems on the Internet block incoming mail from
-# dynamic IP addresses as spam protection.
-
-# A system with a dynamic IP address can receive its own mail, or local delivery can be
-# disabled entirely (except mail for root and postmaster).
-
-# 1. internet site; mail is sent and received directly using SMTP
-# 2. mail sent by smarthost; received via SMTP or fetchmail
-# 3. mail sent by smarthost; no local mail
-# 4. local delivery only; not on a network
-# 5. no configuration at this time
-
-# General type of mail configuration: 1

-# The 'mail name' is the domain name used to 'qualify' mail addresses without a domain
-# name.
-
-# This name will also be used by other programs. It should be the single, fully
-# qualified domain name (FQDN).
-
-# Thus, if a mail address on the local host is foo@example.org, the correct value for
-# this option would be example.org.
-
-# This name won\'t appear on From: lines of outgoing messages if rewriting is enabled.
-
-# System mail name:
-# iank: see comment elsewhere on mailname

-
-# Please enter a semicolon-separated list of recipient domains for which this machine
-# should consider itself the final destination. These domains are commonly called
-# 'local domains'. The local hostname (kd.lan) and 'localhost' are always added
-# to the list given here.
-
-# By default all local domains will be treated identically. If both a.example and
-# b.example are local domains, acc@a.example and acc@b.example will be delivered to the
-# same final destination. If different domain names should be treated differently, it
-# is necessary to edit the config files afterwards.
-
-# Other destinations for which mail is accepted:
-# iank.bid is for testing
-# mail.iankelling.org is for machines i own
