postfix

[Ted Brenner]

Hi all,

I'm trying to setup postfix following this guide. But I'm not able to get a few things to work. 

First, the commands I added to /rw/config/rc.local don't seem to run. Namely, it doesn't appear to be mounting the /usr/local/etc/postfix directory in /etc/postfix. Also postfix doesn't appear to be running on startup. How do we tell if that gets run correctly?

Thanks!

Ted

Did you 'chmod +x /rw/config/rc.local' before restart the vm or try to run sh /rw/config/rc.local to see either it is working or not?

You have to set the executable bit on the script. If you don't do that, the script won't run.

Other have pointed out that you need to set the executable bit on
rc.local.
You might want to cnsider instead the use of bind-dirs :
www.qubes-os.org/doc/bind-dirs which provides similar functionality.

Thanks all. Yes, this was the issue. Still can't get postfix to work but that now appears to be due to missing the aliases.db. 

Is there a reason rc.local isn't executable by default? 

[Ted Brenner]

Quick follow up. What user is running rc.local? Is it root or user? I assume it is user since I'm seeing a permission denied when the call to run postfix tries to access the aliases.db file. So should I throw a sudo in front of the command to start postfix in the rc.local file? Or should I change the permissions on aliases.db? Per the instructions I'm also doing a mount command but that succeeds. Which is odd since if I try it as user, it fails saying only root can do it. Which is why I ask which user is running rc.local.

[Unman]

It's root - you could see this by appending:
echo `whoami` >> /home/user/rc_perms
But I suspect you already know this.

What are the permissions on aliases.db?
What template are you using and do you have selinux enabled?

[Ted Brenner]

Thanks Unman. I'm using Fedora-24 and selinux is not enabled. aliases.db is owned by root:root with rw-r--r--.

I think the source of my problem was that postfix does some initial configuration on its first launch. This requires the postfix-files file. But that didn't get copied to /usr/local/etc/postfix which is mounted over /etc/postfix. Once I added that file it launched successfully which appears to have properly set up the aliases.db file so now all appears to be well. Perhaps I'll submit a PR to update the postfix page to include copying postfix-files to /usr/local/etc/postfix.

I've come across this too and created a PR for the docs: https://github.com/QubesOS/qubes-doc/pull/427
