Problems SPAM filter and procmail permissions

Help! (Home for newbies)

Hi Joe

Now I’ve done a complete reinstall:

  • removing virtualmin using the install script with option --uninstall.
  • tried to install with install script (both GPL and Pro) but it failed to install packages (see error-log, script warns that installation will fail on systems not listed, which is the case)
  • then I followed the steps for manual installation: Downloaded "webmin_1.450_all.deb", "usermin_1.380_all.deb", "webmin-virtual-server_3.66.gpl_all.deb" and "webmin-virtual-server-theme_6.7_all.deb" and installed them using dpkg - went all well, system is now running as before.
  • checked again permissions of procmail -> 6755 (ok)

But I still get the error that setuid/setgid do not work. Do you know how I can test these functions e.g. with a small test script? If it works we can assume that the error is in the procmail-wrapper or the plugin-check…

Attachement didn’t work. But I can send error-log by mail or post it directly if necessary.

23

That’s okay, I wouldn’t expect the installation log to show anything that’d help in this case, since it can’t complete properly on Lenny.

Now, why you’re still getting the error about procmail is a bit of a mystery to me.

I’ll talk to Jamie to see if he has an idea as to what might be triggering the error you’re seeing.

One thing you should check is if Postfix is configured with the correct path to procmail. Try running the following command, and posting the output here :

[code:1]grep mailbox_command /etc/postfix/main.cf[/code:1]

It should be something like :

[code:1]mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME[/code:1]

Hi Eric

I see the only way to resolve the problem by having a look at save_newfeature.cgi which performs the validation (feature_check?) of all features. But I’m too less experienced in pearl programming to reverse-ingeneer it on my own…

Hi Jamie

Yes, that was it! Thank you very much!

Hi

I have the same Problem but i view at Jamies post follow line.

mailbox_command = /usr/bin/procmail -a “$EXTENSION”

on my system i got following

mailbox_command = procmail -a “$EXTENSION”

so i add the path manual. and now it works.

BTW - Love the software!

My /etc/postfix/main.cf reads like this

mailbox_command = /usr/bin/procmail -a “$EXTENSION”

I too were getting the

Failed to save enabled features : The procmail command procmail has 0 permissions, when it should be setuid and setgid to root. Email may not be properly delivered or checked for spam.

error.

To fix my version of this issue i did the following
Change procmail to root from mail group;
–Run from terminal–

root@pluto:~# chgrp root /usr/bin/procmail
root@pluto:~# ls -l /usr/bin/procmail
-rwxr-xr-x 1 root root 72316 2007-03-28 04:35 /usr/bin/procmail

Next step change to setuid as requested run the following command

root@pluto:~# chmod ug+s /usr/bin/procmail
root@pluto:~# ls -l /usr/bin/procmail
-rwSr-sr-x 1 root root 72316 2007-03-28 04:35 /usr/bin/procmail

note the inclusion of the S’s { -rwSr-sr-x }
Now re-run the re-check config and you should not get this error again.

Hope this helps someone and I thought I would share my experince on this issue so next time I go to re-install virtualmin and get this error again, I will know were to come and find the solution for it…

Thanks again for such great software!
