Hi all,
we have a Proxmox HCI Cluster (proxmox-ve 6.4-1, kernel 5.4.114-1-pve) and Ceph 15.2.11. We would like to upgrade to version 7.4.
Can we go in one step from 6.4 to 7.4 with Ceph 15.2.11 and then upgrade Ceph from octopus to pacific ?
Are there any issues to be expected since Ceph...
Meines Wissens ist das "Greylisting" über postscreen "deep protocol tests" realisiert. Es wird die Einhaltung des SMTP Protokolls geprüft und ist nicht zeitbasiert wie postgrey. (http://www.postfix.org/POSTSCREEN_README.html#after_220)
Oder liege ich da falsch @ Proxmox-Team ?!
Unsupervised learning from SpamAssassin rules ( = autolearning ) is enabled. It's efficient & fast. For a site-wide bayesian filter I doubt that any additional (manual) training by users provides better results especially when they provide ham as spam or vice versa. I personally don't see the...
Falls man die Spamassassin Regeln öfters als 1x täglich updaten möchte kann man das per cron erledigen.
Zum Beispiel:
# vi /etc/cron.hourly/sa-housekeeping
# chmod 744 /etc/cron.hourly/sa-housekeeping
#!/bin/sh
SYSLOG_TAG=sa-update
logger -d -p mail.info -t $SYSLOG_TAG "*** Start Spamassassin...
You asked already about whitelists: https://forum.proxmox.com/threads/whitelist-dnsbl.41655/#post-200421
dnswl.org is already integrated into spamassassin.

Post the output of the following commands:
# grep -i KEY /etc/pmg/pmg-api.pem
# ls -la /etc/pmg/*.pem
# openssl x509 -in /etc/pmg/pmg-api.pem -noout -text | grep -i Issuer
To force/replace the certificate to a self signed one you can use the following command:
# pmgconfig apicert --force 1
You can use the pam module: See here https://developers.yubico.com/yubico-pam/
Get a API Client ID: https://upgrade.yubico.com/getapikey/
In debian stretch it's just:
# apt-get install libpam-yubico
Create a yubikey mapping file /etc/yubikey_mappings

What is the output of the test commands above? (if "dig" is not available install the dnsutils package with "apt-get install dnsutils")
Do you have any URIBL_BLOCKED in your mail.log since you changed your dns?
RTFM:
You can find the default templates in /var/lib/pmg/templates/.
Copy the templates you need to /etc/pmg/templates/, then apply your changes there.
After that run:
# pmgconfig sync --restart 1
=> see 4.3. Service Configuration Templates
That was just to show that Hetzner DNS does not work with (Spamhaus) DNSBL in response to @DerDanilo message.
If you have installed and configured bind as I explained than you are ok. The mailgateway should now detect the spam.
This commands should always return the IP of your local DNS:
# dig...
use your own DNS resolver - Hetzner does not work
EDIT: (the first 3 are Hetzner DNS Server)
# dig +short @213.133.98.98 2.0.0.127.zen.spamhaus.org
# dig +short @213.133.99.99 2.0.0.127.zen.spamhaus.org
# dig +short @213.133.100.100 2.0.0.127.zen.spamhaus.org
# dig +short @mylocaldns...
With a public DNS u hardly detect any spam. Use a DNS resolver (bind)
