Notifications SMTP postifx settings apply fails

odragon · 14. Juli 2022

Greetings,

I tried to setup notifications (did not have any before) but I am unable to apply the settings after saving them. It appears to fail a step called `postfix_set_permissions`.

Helios 4

Debian 11 Bullseye

OMV 6.0.31 (upgraded from v5 on Buster a few months ago without noticing other issues)

Stacktrace and system report attached. Let me know if I forgot some information.

Can anyone else reproduce this? Any ideas how I could debug and/or fix this?

Thanks.

Someone else seem to have had a similar issue, but it went unnoticed/ignored.

Google SMTP settings for the host you are trying to use. Also here are a few threads that might help:

SMTP notifications does not work anymore

Hi !

For some time, I realized that sending SMTP notifications no longer works.
My setup with gmail used to work, but it longer does.

My config is:

SMTP server: smtp.gmail.com

SMTP port: 587

Encryption method: STARTTLS

I share you my Syslog

Email notifications not working with Gmail

Hi all!

I'm having nightmares trying to make the amazing OMV Notification Plugin working with Gmail. No problem with the plugin, but Gmail (bad Google, no donut for you!). After some internet digging, I realize this is something related to Gmail SMTP security policies which could be solved using some kind of certificate (or something like this).

I wonder is someone here had this pain in neck and could manage to solve it, would like to share the journey. Maybe I'll give to you the Google's…

Opening port on OMV to local hosts

I have my ISP's SMTP relay server set in OMV's Notifications section (OMV5). This works fine - notifications arrive, bash scripts can use "mail -s", and Python programs running on OMV can send using the smtplib module when specifying 'localhost' as the server.

I would also like to be able to send via OMV from Python programs on other hosts in my network, i.e. using <myomvservername> (it is defined in my local DNS) as the smtp server name. When I do that though, I get "[Errno 111] Connection…

Hi Agricola and thanks for the reply.

I'm using my ISP's SMTP server, and it works great for both pfSense and Nextcloud. I don't think it's a problem with the settings. OMV seems to be having issues setting permissions on something (see log in first post). Since I can't "Apply" or "Confirm" settings, the notifications don't get enabled. There's nothing in syslog.

Here's my /etc/postfix/main.cf if it's any use. The folder and all files in it are owned by root.

So notifications worked fine when it was on OMV5? How did you upgrade?

What is the output of

postfix set-permissions?

That is the command that failed

Code

No. I did not have notifications set prior to now.

What is the output of

postfix set-permissions?

The output is the following:

postfix: fatal: parameter inet_interfaces: no local interface found for 127.0.1.1

That would indeed explain the error. My localhost is 127.0.0.1:

Code

odragon@omv:~$ ifconfig
...
lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 688542  bytes 284158440 (270.9 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 688542  bytes 284158440 (270.9 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Why does postfix think that inet_interfaces = localhost means localhost resolves to 127.0.1.1?

odragon · 19. Juli 2022

Ah... hostfile. Duh!

Following the trail :

Code

odragon@omb:~$ cat /etc/hosts
# This file is auto-generated by openmediavault (https://www.openmediavault.org)
# WARNING: Do not edit this file, your changes will get lost.
127.0.0.1 localhost.localdomain localhost
127.0.1.1               localhost

Turns out postfix does not like the hostname to be "localhost." Makes sense I suppose. I don't recall setting it to localhost though. Maybe I never set it before and it just used the default value, or it got overwritten during the update from OMV5 to OMV6. Either way, seems like a usability issue with OMV.

Thanks for the help. Notifications work now!
