- Hello, I have been studing sendmail for a while and I am a little
- confused over How sendmail determines what the LOCAL domain name is.
-
- My sVr4 system has the name "sw2020.ki.icl.se". I thougt that this would
- make the LOCAL varible contain "ki.icl.se", but it seems to match both
- "icl.se" and "ki.icl.se"
-
- Here is the definition part of sendmail.cf:
-
-
- Dmki.icl.se
- Dwsw2020
- Cwsw2020 sw2020.ki.icl.se
- Cmki.icl.se
-
- -------------------
-
- This could be wrong :-( if it is, Please tell me how.
-
- What happends is that if i send something off to " user@icl.se" which is
- our toplevel domain, sendmail converts it to "user@ki.icl.se".
-
- What sendmail -bt tells me is as follows:
-
- ADDRESS TEST MODE
- Enter <ruleset> <address>
- > rewrite: ruleset 3 input: "user" "@" "icl" "." "se"
- rewrite: ruleset 6 input: "user" "<" "@" "icl" "." "se" ">"
- rewrite: ruleset 6 returns: "user" "<" "@" "LOCAL" ">"
- rewrite: ruleset 3 returns: "user" "<" "@" "LOCAL" ">"
- rewrite: ruleset 1 input: "user" "<" "@" "LOCAL" ">"
- rewrite: ruleset 1 returns: "user" "<" "@" "LOCAL" ">"
- rewrite: ruleset 0 input: "user" "<" "@" "LOCAL" ">"
- rewrite: ruleset 9 input: "user" "<" "@" "ki" "." "icl" "." "se" ">"
- rewrite: ruleset 9 returns: "user" "<" "@" "ki" "." "icl" "." "se" ">"
- rewrite: ruleset 0 returns: $# "ether" $@ "butler" $: "user" "<" "@" "ki" "." "icl" "." "se" ">"

- As you can se it accept's "icl.se" as LOCAL and then Replaces it with
- "ki.icl.se".
-
- When I comment away the "Dmki.icl.se" macro from sendmail.cf this behaivor
- dissapears. LOCAL gets converted back to "icl.se" again.
- So obviously the "Dmki.icl.se" record makes sendmail use that as its LOCAL
- domain at some point in time. But where does it pick up "icl.se" as a
- synonym for LOCAL. Its not in sendmail.cf.
-
- My domain name in /etc/resolv.conf is "ki.icl.se".
- domainname(1M) returns "ki.icl.se"
-
- Any ideas ?
