Need clarification on whitelist rules

Wed Oct 6 20:17:41 IST 2004

I don't believe it can be done using Postfix. Please correct me if I'm
wrong.

I know it works in sendmail - we use it on many systems;

I believe it can be done in exim. Mike Bacher [mikeb at tulsaconnect.com] sent
me the directions below:

FYI, a potential solution to the white/blacklist problem with MailScanner
when using exim as the MTA:

[I wont have time to test this myself for a week or two]

You can do this with an "incestuous" call to exim. Make this your first
router:

split:
   driver = accept
   domains = the.domains.you.want.to.do.this.for
   condition = ${if eq {$received_protocol}{split}{no}{yes}}
   transport = send_to_self
   no_verify

Add this transport:

send_to_self:
   driver = pipe
   batch_max = 1
   use_bsmtp
   command = /usr/sbin/exim -oMr split -bS
   user = exim

Untested. YMMV. You logs will get bigger, of course...
