- You are doing something that the designers of 'sendmail.{main,subsidiary}.cf'
- did not contemplate. To oversimplify, the config is checking if a local
- host in your domain exists, and if not is displaying this message. But
- the test for existence is a simple gethostbyname() which fails if there
- is no address associated with the host.
-
- Toward the end of 'sendmail.cf' you will find rules approximately
- like this:
-
- R$*<@$%y.LOCAL>$* $#ether $@$2 $:$1<@$2>$3
-
- ... (a few more rules)
-
- R$*<@$*.LOCAL>$* $#error $:Never heard of host $2 in domain $m
-
- Between those two rules you need to insert:
-
- R$*<@=X.LOCAL>$* $#ether $@2 $:$1<@2>$3
-
- and near the top of the config, you need to add
-
- # Define local MX only addresses within our domain.
- CXmr
-
- If your config is based on 'sendmail.main.cf' it would be better to change
- the '$#ether' to '$#ddn'.
