Nice. But if you're running a multi-tennant system, you'll need a way
to map sender/recipient pairs to the inbound. We do that with a
postfix policy server that hooks into the END-OF-MESSAGE stage, which
will provide the SASL authenticated user, and the smtp-envelope
recipient (there are problems with multi-recipients that you have to
work out). Feed this into something like
http://wiki.apache.org/spamassassin/ManualWhitelist and you're good to
go.
As the comments state:
# Postfix quick/dirty auto whitelisting script
:)
That said, with an NFS share it'd be absolutely trivial to modify this script
for a split multi MX/outbound environment, and not much more difficult
without NFS. In the latter case, in short, each outbound node would run the
first line of this current script, each writing a different temp file name,
and scp it to $MX. $MX would run the rest of this script, with line 2
cat'ing out all the temp files. $MX would then scp 'auto-whtlst' to the
other MXen. Pretty straightforward.

I´ve thought on something similar in couple of days. You do not mind
if a use whtlist.sh and make any modification to it.
