# This feature causes sendmail to check with a local DCCM deamon about
# all incoming mail
#
# Use this file by copying it to your sendmail/cf/feature directory
# and by adding a line like the following to your sendmail.mc configuration
# file:
#	`FEATURE(dcc)'
#
# To change the default milter failture settings or timeouts as described
# in the sendmail milter README file, use something like:
#	`FEATURE(dcc,``F=T, T=C:30s;S:30s;R:30s;E:30s'')'
# The default parameters wait 30 seconds for the initial connection from
#   sendmail to dccm (C), 30 seconds sendmail sending (S) as well as receiving
#   responses (R) from dccm, and 30 seconds for dccm to check the message
#   at its end (E).
#   Adding "F=T" to the parameters cases sendmail to give SMTP clients
#   a temporary failure when dccm fails.  "F=R" causes sendmail to reject
#   mail when dccm fails.  When neither "F=T" nor "F=R" is present, sendmail
#   quietly accepts the message if dccm fails or is absent.
#   (A failure by dccm would be a serious bug.)
#   misc/hackmc changes the default to "F=T".
#
# To use common directories and whiteclnt files for mail relayed to domains
#   listed in /etc/mail/relay-domains, use a third argument as in
#	`FEATURE(dcc, , ``local'')'
#   If domain.com is in the relay-domains, file, then mail for all users
#   forwarded there will use userdirs/local/domain.com/whiteclnt and
#   userdirs/local/domain.com/log.
#
# To connect dccm to sendmail via TCP or use a UNIX domain socket
# other than @dcc_rundir@/dccm, or other fancy changes, consider modifying
# this file or the resulting sendmail.cf file.
#
# See also @libexecdir@/hackmc
