Re: Fastforward AND smarthost-style operation at once
I'm working on a similar situation. I had tried what Dave suggested and it worked as documented. However, I need to be able to actually relay messages that don't match an alias (ie. don't rewrite the recipient address). My normal config: I have my qmail box acting as my primary MX and behind that sits my Domino server running SMTP. My rcpthosts has: kendle.com My smtproutes has: kendle.com:mail.kendle.com locals has only the machine itself. So any message for kendle.com is relayed to mail.kendle.com (the Domino server), which accepts messages for recipients @kendle.com. Here's what I tried: I put kendle.com in locals and used a .qmail-default like this: | fastforward -p /etc/aliases.cdb | forward "$LOCAL"@mail.kendle.com messages are forwarded to [EMAIL PROTECTED] instead of [EMAIL PROTECTED] If I use: | fastforward -p /etc/aliases.cdb | forward "$LOCAL"@kendle.com the message just loops because qmail-send thinks that kendle.com is local. I know it's sort of nitpicky, but I need messages to be processed through fastforward and be relayed to the next server with the recipient address of [EMAIL PROTECTED] if no match is found. Any ideas? Thanks, Josh
RFC821 bounce compliance
Hi all, Long story short here. I need to convince a business partner's admin that we are correct in sending their users bounce messages with a null envelope sender. The partner is using Exchange and they are relaying a bounce message from us to one of their internal non-M$ systems and rewriting the envelope sender to unknown. M$ acknowledges the problem, it is documented. The partner admins will refute the M$ document (it has happened before!) and continue to assert that our MTA is to fault for this. I hate doing other people's work. Now, we all know that's the correct way to do it, but I went to RFC821 to back me up. RFC821 states that this is "permissible". Fair enough - if it's "permissible" then a compliant MTA that receives such a message should be able to deliver or relay as appropriate. Permissible implies to me that you may choose to use that feature, but you MUST support it when used by another MTA delivering a message to yours. I think my argument is sound here. My real question is the reference in 821 (page 15) that the sender (apparantly header sender) is server-SMTP. Now typically this is mailer-daemon. Does this RFC really say that I should be using some form of `cat /var/qmail/control/me`-SMTP instead? I really don't think it matters in practice, but I want to have my ducks in a row when I take my position. Bottom line: Should I change my bouncefrom if I want to stand by the RFC 100%?

Re: How to grab the envelope contents while filtering?
Actually, I was looking at the release notes, not the man page, but yes I
should have known that from version 1.0. Thanks.
As for the empty messages, I found that if my filter has no output a blank
message is sent to the envelope recipients. I circumvented by this
modification to qmail-qfilter.c v1.0:
/* remap the appropriate FDs and exec qmail-queue */
int run_qmail_queue(int tmpfd, int envpipe[2])
{
struct stat mystat;
struct stat *ptr_mystat;
ptr_mystat=mystat;
fstat(tmpfd,ptr_mystat);
if (mystat.st_size 5){
if(close(envpipe[1]) == -1 ||
dup2(tmpfd, 0) != 0 || close(tmpfd) == -1 ||
dup2(envpipe[0], 1) != 1 || close(envpipe[0]) == -1 ||
close(2) == -1)
return QQ_WRITE_ERROR;
execl(QMAIL_QUEUE, QMAIL_QUEUE, 0);
return QQ_INTERNAL;
}
return QQ_SUCCESS;
}
It's kind of a hack, but it works so far. Should I continue to use this method or is
there a better solution here?
Thanks again for all your help and patience with a newbie. :)

The same man page tells you that qmail-qfilter sets QMAILUSER and
QMAILHOST to the username and hostname portions of the envelope sender.
Dropping empty messages is something you can do in your filter.

Re: How to grab the envelope contents while filtering?
I have a filter the looks at file attachments in the message. If certain file types are attached, the message delivery is stopped (ie. no output from the filter). Without the qmail-qfilter hack, qmail-queue gets only the envelope and sends what amounts to an empty message to the envelope recipients. With the hack, if the message is 5 characters, qmail-queue is not run.

Re: How to grab the envelope contents while filtering?
I saw that in your example, but it causes a delivery failure, which is not what I want to happen. I need the message to be accepted and silently dropped if it meets certain criteria. I do the appropriate notification on the back end. I suppose qmail-qfilter can be patched so that qmail-queue is not run on a specific filter exit code, no?

How to grab the envelope contents while filtering?
Hi all, I'm using a content filter shell script that I've written (based on inflex) with qmail-qfilter. During this filter process, I'd like to grab the contents of the envelope and store them in a file for use later (ie, reconstructing the envelope for an inject). I've toyed with trying to pipe fd 1 into a file without success. I know that this has to be doable with a small C program, but quite honestly, I don't have the familiarity with C to do it. Can it be done with Perl? In the shell? Is it as simple as reading fd1, writing a file, and re-writing fd1? Any ideas on how I can accomplish this?

RE: How to grab the envelope contents while filtering? - syntax error
OK, so I tried this:
#!/usr/bin/perl
if ($#ARGV != 0) {
die "Usage: $0 outputfile\n";
}
open (INFD, "1") or die "BAD FD IN";
open (OUTFILE, "$ARGV[0]") or die "BAD FILE OUT";
# open (OUTFD, "1") or die "BAD FD OUT";
while (INFD) {
print OUTFILE "$_";
# print OUTFD "$_";
}
close (OUTFILE);
close (INFD);
# close (OUTFD);
I tried as is and with the commented lines enabled (just to be sure I didn't step on
my input for some silly reason). I still end up with a 0 byte
output file, same as
using redirection in the shell. The more I think about it, I'm almost certain that my
script does not have access to this data (so to speak) when run
via qmail-qfilter.
I think it's time to go back to the drawing board and go dig in the qmail-qfilter
source. Any more ideas, concurrences, disagreements, etc?
Thanks,
Josh

RE: How to grab the envelope contents while filtering?
This is fine. I think the qmail-inject might be overkill, but does no harm.
With the -n, it merely prints the message (with some headers tidied up if
need be), which is then pumped into qmail-queue. The recipients are coming
from the envelope (the fd 1 magic that I'm trying to figure out), not from
the header. Therefore, no extra or double recipients.
Your concern is my reality :(. When an administrator needs to resubmit a
message that was stopped by the filter, we need to reconstruct the envelope
as it was at the time that the message was stopped. Now, if I just inject
the message, it's gonna go out to everybody in the header all over again.

MAN PAGE ALERT
(from qmail-qfilter page)
qmail-qfilter sends the message text through each of the
filter commands named on the command line. Each filter is
run seperately, with __standard input__ opened to the input
email, and __standard output__ opened to a new temporary file
that will become the input to either the next filter, or
qmail-queue. Each filter on the command line in seperated
with --.
With this data in mind, I made a little script that does some censoring
--- qmail-qfilter myfilter.pl -- qmail-inject -n ---
--
#!/usr/bin/perl
while () {
s/fuck/fsck/i;
print $_;
}

PS - I'm concerned that with this qmail-inject thing going on that multiple
recipients might get multiple copies - but then I haven't read the
documentation enough to clarify that in my head. Would a relayed message
to
multiple recipients have those other recipients re-qualified as
undelivered-to and hence would get multiple copies? Somebody knows, I'm
sure.
