Debugging spamd/spamc interaction

[Dirk Kuypers <dk...@comnets.rwth-aachen.de>]

Hi,

we want to migrate our old mailserver (Sun E450 with Solaris 2.7, sendmail and 
SA 2.64) to a Linux rack-server with debian linux, qmail and SA 3.x  on it. 
Now the new box is up and running so far and I wanted to test it first with 
spamd/spamc to compare the more or less vanilla SA 3 performance with our old 
setup of 2.64 with lots of custom rule-sets (but which gets more and more 
outdated and annoys me;-).

I started spamd from the command line:
in:~# /usr/sbin/spamd --create-prefs --max-children 5 --helper-home-dir -A 
137.226.4.0/24 -D --pidfile=/var/run/spamd.pid
trying to connect to syslog/unix...
no error connecting to syslog/unix
logging enabled:
        facility: mail
        socket:   unix
        output:   syslog
creating INET socket:
        Listen: 128
        LocalAddr: 127.0.0.1
        LocalPort: 783
        Proto: 6
        ReuseAddr: 1
        Type: 1
debug: SpamAssassin version 3.0.2
[...]
logmsg: server started on port 783/tcp (running version 3.0.2)
logmsg: server successfully spawned child process, pid 4886
logmsg: server successfully spawned child process, pid 4887
logmsg: server successfully spawned child process, pid 4888
logmsg: server successfully spawned child process, pid 4889
logmsg: server successfully spawned child process, pid 4890
server pid: 4884

So at least everything seems to be running. But when I try to connect from 
another machine, I get the following errors:

dk@brucez:~/Documents> spamc -d gin -l < SPAM.vanilla
spamc: connect(AF_INET) to spamd at 137.226.4.160 failed, retrying (#1 of 3): 
Connection refused
spamc: connect(AF_INET) to spamd at 137.226.4.160 failed, retrying (#2 of 3): 
Connection refused
spamc: connect(AF_INET) to spamd at 137.226.4.160 failed, retrying (#3 of 3): 
Connection refused
spamc: connection attempt to spamd aborted after 3 retries

But: I don't get an entry at the log files of the spamd host. I can't even 
test it on gin itsself, the same result.

What can I do to debug this situation? Why is the spamd host not listening? Is 
it because of qmail? I think it get's somehow started with qmail-scanner 
normally, but I am not the one configuring the mail-server...

Thanks for any help
	Dirk
