This is beginning of my cf/rrouter.cf, implementing functionality
somewhat like IDA sendmail global aliases. It's not perfect
(address should exactly match one in galiases db to be replaced), 
but it's simple one.


provide rrouter

envelopeinfo=(message-id "<$USER.interactive@$hostname>" now 0)

: ${UNRESOLVABLEACTION:='error unresolvable'}

if [ -f $MAILVAR/db/galiases ] ; then
	relation -lmt unordered -f $MAILVAR/db/galiases glob_alias
else
	glob_alias() { return 1 }
fi

rrouter (address, A) {
	local tmp tee seenuucp

	# Do global aliases expanding
	$(get $A recipient) && 
		sift "$address" in
			.*|.*	;;
			.*
				tmp=$(glob_alias $address) &&
				address=$tmp ;;
		tfis

	seenuucp=false
	...



Here is fragment from db/galiases:

#Old address									New address
hospital@hospit.stavropol.su	aihastavropo@glas.apc.org



Now try this:
