Notifications: Overload of Email Messages

starbudder · Jan 28th 2026

Over the past year, starting with OMV7 and now OMV8, that I am being overloaded in notification messages to the point where over 500 are attempted and no longer sends but a few on a reboot since my upgrade to OMV8. Its been 8-months or so since email messages were only sent on a reboot. I currently have over 100,000 pages of messages in my logs. The email notifications I was receiving are old events going back to the last summer.

How do I remove the 100,000+ pages of messages from the logs?

How do I fix the notification system so the emails are sent as the event occurs, not from events months before and the messages are sent immediately not only at a reboot.

Try: sudo postsuper -d ALL

votdev · Jan 29th 2026

Do you have email notification enabled? If disabled, there is a cron job that automatically clears the postfix backlog.

When you get old emails, is it possible that you have installed flashmemory or writecache plugin? I remember a user that has the same problem which finally was caused by one of those plugins.

starbudder · Jan 29th 2026

I ran sudo postsuper -d ALL

It deleted 43 messages.

I decided to try sending a test message from Notifications. I immediately got he failed message warning to check the logs.

The logs indicated many messages repeating like: My Daily user sending limit exceeded.... For more information on Gmail 550-5.4.5 ....... delivery suspended, too many login attempts....

I then decided to run the sudo postsuper -d ALL command again, this stopped the creation of new messages.

I did received via Gmail about 60 emails with the messaging described above with the title Undelivered mail return to Sender title on them.

Any ideas? Maybe I need to wait until tomorrow before attempting a new test message to see if Gmail will accept new messages?

After a restart of my OMV PC I am continuing to see the following messages created:

postfix/smtp[6171]: BB3342C0569: replace: header Subject: Monitoring alert -- Exists nginx: Subject: [OMV.local] Monitoring alert -- Exists nginx

postfix/smtp[6171]: BB3342C0569: to=<dickxxxxxx@gmail.com>, relay=smtp.gmail.com[142.250.99.108]:587, delay=518, delays=451/66/0.33/0.81, dsn=2.0.0, status=sent (250 2.0.0 OK 1769717989 d9443c01a7336-2a88b3eecc5sm59841945ad.17 - gsmtp)

postfix/smtp[6171]: 7E4142C049B: replace: header Subject: Monitoring restart -- Does not exist nginx: Subject: [OMV.local] Monitoring restart -- Does not exist nginx

These messages repeat many times for over 60 - 70 total messages and emails to me.

Hoping someone can provide advice to me for a solution

That looks all ok. Do you still have recent log entries regarding nginx?

starbudder · Jan 30th 2026

I still get them when I reboot my system, which is producing the repeated messages:

......... replace: header Subject: Monitoring restart -- Does not exist nginx: Subject: [OMV.local] Monitoring restart -- Does not exist nginx

and

.........replace: header Subject: Monitoring restart -- header Subject: Monitoring alert -- Exists nginx: Subject: [OMV.local] Monitoring alert -- Exists nginx

In the Memory log over 20 pages before stopping and these are also sent as emails (about 55 emails) to me with various old dates going back to May 2025. This is reduction from the last time I rebooted the system.

macom · Jan 31st 2026

......... replace: header Subject: Monitoring restart -- Does not exist nginx: Subject: [OMV.local] Monitoring restart -- Does not exist nginx
and
.........replace: header Subject: Monitoring restart -- header Subject: Monitoring alert -- Exists nginx: Subject: [OMV.local] Monitoring alert -- Exists nginx

These mail are coming from the monitoring system. The first one is mentioning that nginx, that is the webserver for showing the GUI of OMV, has not started. The monitoring system is then trying to start nginx.

The second mail is telling that his was successful and that nginx is now running.

So here is the question, why nginx is not starting or only after the monitoring system has started.

Quote from starbudder

and these are also sent as emails (about 55 emails)

Does this mean, you get these same ~55 mails at every reboot?

starbudder · Jan 31st 2026

Yes I just rebooted and got another 57 emails as above. Also as I mentioned above they are mainly old dated messages as either nginx i starting, or does not exist..., in this reboot the emails are spread out back to April 2025.

The last email time stamped and dated this morning is: RE: [OMV.local] Monitoring restart -- Does not exist nginx

After the last two reboots, after running the omv-salt deploy run nginx phpfpm command I no longer get other old emails.

ryecoaaron · Jan 31st 2026

if you have the writecache plugin installed, disable it and reboot to see if you still have the emails.

macom · Jan 31st 2026

Try sudo postfix flush to flush/purge all mails in the queue.

You can have a look at the mail queue with mailq

starbudder · Jan 31st 2026

After disabling the writecache plugin and then rebooting , another 60 plus emails as above arrived.

After running cmd sudo postfix flush then rebooted, no more emails! Success!

However new issues:

Saw the new OMV update available to update from OMV 8.0.8 -1 to 8.0.9-1 . Attempted but Will not upgrade. Note this is my first attempt to update since I upgraded from OMV7 to OMV8.

Also tried in notifications to send a test email. Will not, get the 500 Internal Server Error window Failed to send email. This was working.

Thank you for your advice, hoping for more.

macom · Jan 31st 2026

Post the output of omv-upgrade in a code box.

Did you run the fix7to8upgrade script after you release-upgraded from OMV7 to OMV8?

starbudder · Jan 31st 2026

will re run ovm-upgrade and post

No I did not run fix7to8upgrade script

That seemed to work from the CMD prompt, updated to 8.0.9-1 successfully.

Usually I do updates from the WebGUI

Test email still will not send and the normal update emails.

starbudder · Jan 31st 2026

Should I run the fix7to8upgrade script ?

ryecoaaron · Jan 31st 2026

can't hurt.

That is the correct way. But sometimes you get better information when you run the update from the CLI.
