dspam.sock permissions

[aws910]

I've been hacking my way through a UntuntuServer7.10+postfix+dspam+webui installation as a relay, and I've almost got everything working together. Here's the last problem(I hope) and I can't figure it out:

When I try to send an inbound test message via telnet to port 25, it doesn't come through. when I run "mailq" from the console, I get this:
13D0311AF51 397 Thu Nov 1 02:59:17 xxx@outsidedomain.com
(connect to newserver.newdomain.com[/var/spool/postfix/tmp/dspam.sock]: No such file or directory)

I've figured out how to edit the dspam.conf to put dspam.sock where I want it(and I verified that it actually is there), but postfix "can't find it" no matter where I put it. How should I set the permissions/ownership for this file? I don't want to give it too many permissions and screw up the chroot-jailing of postfix.

Are you sure that DSPam is really running? You can check that with ps aux

[aws910]

It's possible, I just assumed it was running because it would create the dspam.sock file. here's the output of ps aux:

also, when I run a "locate dspam.sock", I get this:
/var/spool/postfix/dspam.sock
/var/spool/postfix/tmp/dspam.sock

btw Falko, I really appreciate all the HOWTOs and your help in all this. You've got a wonderful site, I'd still be a windoze-slave if it weren't for you. :D

[falko]

Looks ok. My best guess now is that your Postfix is running chrooted (what's in your /etc/postfix/master.cf?) and therefore looks for the socket within /var/spool/postfix (so /var/spool/postfix/dspam.sock would translate to /var/spool/postfix/var/spool/postfix/dspam.sock).

[aws910]

Sweet, it works now. I guess I didn't fully understand the meaning of chrooting before.

On my fix... here's the line from my /etc/postfix/master.cf:
smtp inet n - y - - smtpd
-o content_filter=lmtp:unix:/tmp/dspam.sock
...the corresponding line from my /etc/dspam/dspam.conf:
ServerDomainSocketPath "/var/spool/postfix/tmp/dspam.sock"

Thanks again, Falko. Next time you're in Los Angeles, there's a cold one waiting for you here!
