It sounds to me like the original scoring is correct, as it does not hit the NO_RELAYS rule, and that takes place in step 2. An easy way to check what's in the message at steps 2 and 4 would be to add an always_bcc directive to /etc/postfix/main.cf, which will send a copy of every mail message that passes through Postfix to a nominated mailbox. If amavis is being run as a Postfix service, i.e. using sendmail to re-inject the scanned message into the Postfix mail queue, then always_bcc will capture two copies of the message - (1) after delivery to Postfix and (2) on redelivery to Postfix after its been through amavis. You can then use procmail and/or mboxgrep to search through the captured messages. Martin

No. While (I believe) Amavis actually can use spamd, it is most common not using it. Amavis uses its own instance of SA, *similar* to what spamd does. Also, in that case, SA doesn't add headers, but Amavis code does. Moreover, SA generally does not modify any headers but the Subject if specifically configured to do so, and there are a very few rarely-used options for rewriting (two) other headers. None of these ever harms Received headers. Suggestion: After each step of your mail processing, if you can, save a copy of the mail to a log file.

What we do *not* know is, where exactly after that headers get lost. Some verbose logging of headers before and after *all* following stages will be necessary. Also it is left kind of unclear, how and where you got the mail with the headers lost for re-feeding to SA.

I'm afraid I'm going to have to side with the people who suggested that something in the above steps is deleting headers. Postfix is pretty much guaranteed to add at least one Received header, even if it is just 'Received from localhost'. so if you can guarantee that Step 1 is being done, then something in a later Step is removing headers.
