Hi,
Bit stuck with this one - any help most welcomed :)
In a nutshell: can a redirect router check if the [sender SMTP host]
(not [sender domain] ) is NOT in a [local relay hostlist]?
Why?
====
I want to give the kids email accounts - with moderation + sender
address whitelisting.
So I have set up mailman with a list per kid. Each list is moderated,
non member posting allowed and the only "member" is the kid's local
physical account.
This works really well - only job left to do is to block said physical
account from receiving mail from the outside world - or better, redirect
that address to the list address.
eg
"Real" account is [email protected]
List and "public" address is [email protected]
[email protected] is the only member of "fred" and me+SWMBO are the list
moderators.
So I think I want a second aliases type redirect router that only fires
if the sender host is != (relay hostlist). Mailman is local and will
fall in the scope of the relay hostlist so stuff it sends on to
[email protected] should be handled normally.
Outside mail addressed to [email protected] should be redirected to
[email protected]
This does sound exactly like a second aliases redirect router with an
additional check_local_user test - but with the complication of a test
for the SMTP sender host that I cannot see documented in the private or
generic options - and it's not clear to me if a "condition" check could
test this...
I could forget this and just do an ACL that blocks a list of addresses
if sender != +relay_from_hosts, but now I'm curious about the above
approach...
Many thanks :)
