spam slightly finds its way to the users

[tecra]

Hello

I've installed the proxmox standard filter ( single domain )
The first 3months of the mailgateway worked perfectly.

Now, more and more spam is accessing the accounts.

I already increased the spam-filter to 3, but still more and more spams are comming through...

The Office hour scheme, stands to 0:00 / 23:59 is that correctly?

further, i did not change a single thing ...

somebody has an idea?

best regards...

Tecra

Hi Tecra,

Please check if you changed anything on your Proxmox and/or on your network.

If everything is ok, please verify that you enabled:

- greylisting
- SPF (also deploy a valid SPF for your domain, see http://www.openspf.org/)
- RBL checks
- Receiver Verification

As a common rule, spam in europe is quite low during summer, increasing in winter again - but not for all domains and always changing.
