Hullo
I've been a happy user and recommender of postfix for about 8 years
now. I've tried to work out what's wrong in my situation through the
documentation, but failed. Must be something obvious, I'm sure.
For historical reasons, I was using the Delivered-To: header as part
of an IMAP Sieve rule. However, I seem to have lost this header in my
inbound mail. I'm using Cyrus IMAP as my Message Store and Spambayes
as a content filter. Cyrus is driven through LMTP. I'm using a fedora
build of postfix "postfix-2.5.6-1.fc10.i386". I also have postfix on
a firewall (postfix-2.2.11-1.rh8), which I used to use to forward mail
to my more current system. However, the firewall MTA now merely
forwards to the 'internal' MTA. I'd guess that the firewall MTA used
to prepend the Delivered-To: header, but I haven't been able to check
that.
The problem that I have is that I cannot get that Delivered-To: header
reinstated. I've changed the smtp entry in master.cf to:
smtp inet n - n - - smtpd
-o content_filter=spambayes:dummy
and added the spambayes entry:
spambayes unix - n n - - pipe
flags=O user=tim argv=/usr/local/bin/sbwrapper.sh ${sender} $
{recipient}
I've added the following to main.cf as recommended:
spambayes_destination_recipient_limit = 1
Although it doesn't seem to make much difference.
The flags=O.... in master.cf gives me an X-Originally-To: mail header
and there's no 'Delivered-To:' header, but if I change it to
flags=D...., mail gets bounced by the loop detection code.
I see from the documentation that some loop detection logic may have
changed around version 2.3, but I don't think that the Delivered-To:
header was removed. So I must be doing something wrong as I either get
no Delivered-To: headers (flags=O), or 'too many' (flags=D).
There's no particular reason for trying to generate the Delivered-To:
header through the callout to the content filter, but it seemed an
easy place to plug it in. I can see that I could have misinterpreted
the meaning of the prepend_delivered_header key, which I leave
untouched, but it's not obvious to me how.
I've tried the debugging suggested, but I cannot see any Delivered-To:
header at all.
Hoping someone can help, even if it's just to point me at something
that says that Delivered-To's dead so that I can rework what I want to
do.
