If your filter is bouncing the message as SPAM, then you can whitelist it in
SpamAssassin using the whitelist_from directive in your SpamAssassin conf file.
If however it is being blocked because your filter doesn't like the attachment
types sent to it, or for some other reason calls action_discard or
action_bounce, then you have to code the exceptions into your filter - see the
example below.
Note however that this will literally allow ALL mail through from the
whitelisted addresses - if you still want to scan for spam and viruses, you'll
need to structure your filter_end to do the necessary exception check around
whatever bits you don't want to include for whitelisted addresses.
If you want to whitelist based on recipient, this will also do so.
At the top of your filter:
==========================
$IncomingWhitelist{'example.com'} = 1;
$IncomingWhitelist{'sender at whitelisted.com'} = 1;
At the top of filter_recipient:
===============================
my @senderparts = split(/@/, $sender);
my $senderdom = $senderparts[1];
$senderdom =~ s/[<>]//g;
if (
(exists $IncomingWhitelist{lc($sender)}) ||
(exists $IncomingWhitelist{lc($senderdom)}) ||
(exists $IncomingWhitelist{lc{$recipient}) )
{
return ('ACCEPT_AND_NO_MORE_FILTERING', "ok");
}
Best Wishes,
Paul.
