Hi Wietse
Thanks very much for the quick response and the helpful info.

First of all, that "From <address>" line is an mbox header that
POSTFIX never sends to milter applications.
OK that makes perfect sense.
----------
Postfix always produces Received: headers that include "by servername
(Postfix) with protocolname", followed by "for <recipient>" if the
message has only one recipient.
The Postfix SMTP server, that is.
If that information is deleted, then you need to examine your
header_checks rules.
Thanks for the suggestion about header_checks, but aren't they implemented
in 'cleanup', i.e. after the before-queue SMTP milter has finished? Also
because the delivered message has the full and correct 'Received:' header,
I'm confident that postfix isn't deleting it.
So, it seems possible that the milter application (smtp-vilter) could be
mangling the headers before it sends them to spamd. I'll try to get a dump
of the dialogue between smtp-vilter and smtpd, in order to clarify this; and
also take look at the source for smtp-vilter.
----------
Mail submitted with /usr/sbin/sendmail gets a Received: header
that looks like:
Received: by servername (Postfix, from userid number)
id queueid; date
which also does not match your quote.
Yes that's correct, I'm submitting the mail into smtpd over the network.
Many kind regards
MARTIN
