+# virtualdomains - This is a list of all virtual domains. A virtual domain
+# is much like a local domain, execpt that the delivery location
+# and allowed set of users is controlled by a virtual domain
+# alias file and not /etc/passwd. Wildcards are permitted
+
+# This file lists the virtual domains that this host should handle. The
+# format is
+# host: user=user group=group directory=dir
+# Host may be a wildcard.
+# User/Group are the symbolic names of the uid/gid to operate under when
+# performing deliveries for this name. These should not be root!
+# Directory is the directory to look in for data files. The directory and
+# files may be group writable. The first file to lookup is DIR/aliases
+# which is a traditional exim/sendmail alias file. You can specify
+# users, patterns, pipes and filenames. If that fails then
+# .forward-foo is tried, should that fail then .forward-default is tried.
+# Finally the email will bounce.
