Here's mine. I'm doing a lot of virtual doimain stuff.

#                  Runtime configuration file for Exim               #
######################################################################



# This is a default configuration file which will operate correctly in
# uncomplicated installations. Please see the manual for a complete list
# of all the runtime configuration options that can be included in a
# configuration file. There are many more than are mentioned here. The
# manual is in the file doc/spec.txt in the Exim distribution as a plain
# ASCII file. Other formats (PostScript, Texinfo, HTML, PDF) are available
# from the Exim ftp sites. The manual is also online via the Exim web sites.


# This file is divided into several parts, all but the last of which are
# terminated by a line containing the word "end". The parts must appear
# in the correct order, and all must be present (even if some of them are
# in fact empty). Blank lines, and lines starting with # are ignored.

# Whenever you change Exim's configuration file, you *must* remember to HUP  #
# the Exim daemon, because it will not pick up the new configuration until   #

######################################################################


# The Virtual email domains are configured in a manner that is compatible
# with Linuxconf (http://www.solucorp.qc.ca/linuxconf). Linuxconf is a
# great front end menu system for configuring a lot of settings including
# sendmail, which he added vdeliver for virtual email delivery. The
# linuxconf directory structure is widely accepted as a standard for
# virtual email and there are a number of POP servers that are compatible
# with it. The director structure is as follows:

# Alaises/passwd/shadow:
# /etc/vmail/aliases.$domain
# /etc/vmail/passwd.$domain
# /etc/vmail/shadow.$domain

# Virtual Mailboxes:
# /var/spool/vmail/$domain/$localpart

# Virtual Home:
# /vhome/$domain/home/$localpart

# A list of virtual aliases is kept in /etc/vmail/vdomains

# qualified "official" name of your host. If this option is not set, the
# uname() function is called to obtain the name.

primary_hostname = darwin.ctyme.com


# Specify the domain you want to be added to all unqualified addresses
# here. An unqualified address is one that does not contain an "@" character
# followed by a domain. For example, "caesar@???" is a fully qualified
# address, but the string "caesar" (i.e. just a login name) is an unqualified
# email address. Unqualified addresses are accepted only from local callers by
# default. See the receiver_unqualified_{hosts,nets} options if you want
# to permit unqualified addresses from remote sources. If this option is
# not set, the primary_hostname value is used for qualification.

# qualify_domain =


# If you want unqualified recipient addresses to be qualified with a different
# domain to unqualified sender addresses, specify the recipient domain here.
# If this option is not set, the qualify_domain value is used.

# qualify_recipient =


# Specify your local domains as a colon-separated list here. If this option
# is not set (i.e. not mentioned in the configuration file), the
# qualify_recipient value is used as the only local domain. If you do not want
# to do any local deliveries, uncomment the following line, but do not supply
# any data for it. This sets local_domains to an empty string, which is not
# the same as not mentioning it at all. An empty string specifies that there
# are no local domains; not setting it at all causes the default value (the
# setting of qualify_recipient) to be used.

# recommended for today's Internet.

# local_domains_include_host_literals


# The following line prevents Exim from recognizing addresses of the form
# "user@???" that is, with a "domain literal" (an IP address)
# instead of a named domain. The RFCs still require this form, but it makes
# little sense to permit mail to be sent to specific hosts by their IP address
# in the modern Internet, and this ancient format has been used by those
# seeking to abuse hosts by using them for unwanted relaying. If you really
# do want to support domain literals, remove the following line, and see
# also the "domain_literal" router below.

forbid_domain_literals


# No local deliveries will ever be run under the uids of these users (a colon-
# separated list). An attempt to do so gets changed so that it runs under the
# uid of "nobody" instead. This is a paranoic safety catch. Note the default

# By default, Exim expects all envelope addresses to be fully qualified, that

#
# receiver_unqualified_hosts =

# and/or qualify_recipient (see above).


# By default, Exim does not make any checks, other than syntactic ones, on
# incoming addresses during the SMTP dialogue. This reduces delays in SMTP
# transactions, but it does mean that you might accept messages with unknown
# recipients, and/or bad senders.

# Uncomment this line if you want incoming recipient addresses to be verified
# during the SMTP dialogue. Unknown recipients are then rejected at this stage,
# and the generation of a failure message is the job of the sending host.
