I am running Ubuntu 11.04 as a SOHO server with
postfix/dovecot/Amavis-new/Spamassassin/Clamav setup as my email service.
Does anybody know of a program... that can white list inbound email
based upon the addresses of emails that have been sent?
This simple 7 line bash script does the trick superbly on Debian. Thus it
should work fine on Ubuntu as well.

Drop it in an executable search path, then do a chmod +x and follow the
instructions in the file.
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.
