If you haven't already done so, add the new macro and the new rule set to the client.cf file:
# Defined macros D{REMOTE}mailhost # The name of the mail hubD{HUB}mail.us.edu # Hub as known to the outside world
new
Remember to replace mail.us.edu
with a real hostname - the
name of the hub machine at your site.
The new rule set looks like this:
SHubset # Rewrite the sender for the hubR$- $@ $1@${HUB} user -> user@hub
new
Now test the new rule by running sendmail in rule-testing mode:
%./sendmail -Cclient.cf -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked) Enter <ruleset> <address> >
At the prompt, specify rule set 3 first because
all addresses are preprocessed
by that rule. Then specify Hubset
,
because the hub delivery
agent definition specifies that rule in its S=
equate.
>3,Hubset you
Following the list of rule sets, give the sender's name. Remember that the lone login name will be rewritten to appear as though it is from the hub. The output produced by sendmail looks like this:
rewrite: ruleset 3 input: you rewrite: ruleset 3 returns: you rewrite: ruleset 199 input: you rewrite: ruleset 199 returns: you @ mail . us . edu
Note that V8 sendmail internally changed the name Hubset
into
the number 199.
