That will only show the number of matches. To print the matched lines themselves, add --print-all-matched. Once set up, you use fail2ban-client (rather than fail2ban-regex) to administer a running fail2ban instance (e.g. manually add/remove blocked IPs). You can see from your fail2ban-client...

Your output shows your regex test on a logfile and then presumably part of your local jail.local config. All being well, fail2ban will log everything including Bans/Unbans to /var/log/fail2ban.log. I believe you can/could configure logging to go to systemd journal. Check 'logtarget'. To see...

I believe some /etc/ files, that are potentially overwritten by pmg, have something like 'auto-generated' somewhere near the top. I don't know of a definitive list. PMG doesn't overwrite spamassassin's custom.cf. Nor does it touch any supplemental files you might have created by way of...

I was not sure if it was related to the recent locking down of postfix (in PMG and third party servers). The mail was accepted by PMG presumably because the same restriction aren't applied to the local smtpd port. Or at least not in my config! I suspect it is caused by the way the mailclient...

It was accepted by PMG on the local smtpd port, then rejected by third party server.

The email concerned was an html quoted reply to an html email, to which I attached 2 PDFs. I tried several times to get it accepted. I am guessing it was something in the quoted html message or the way the mail client quoted that meesage? PMG accepted the message on each occassion, but the...

I've configured PMG to use a single relay (smarthost). I recently saw a rejected mail with the response: 552 Message contains bare CR and is violating 822.bis section 2.3 (in reply to end of DATA command) I changed my mail client to use plaintext and the mail was accepted. I guess this is a...

Configuration changes made in the GUI are applied to the relevant services's config files (e.g. /etc/postfix/main.cf) by pmgconfig. This means, if you edit directly any of the generated files (such as /etc/postfix/main.cf), and subsequently make changes via the GUI, your changes will be...

Glad you have it working. However postfix customisation needs to be done in the copied template. Copy the entire main.cf.in template from /var/lib/pmg/templates/ to /etc/pmg/templates/, add your config and then apply the new config with pmgconfig sync --restart 1 Otherwise your customisation...

You need the postfix-pcre package installed. Also, specify the lookup in main.cf (note the pcre prefix): virtual_alias_maps = pcre:/etc/postfix/virtual On PMG this should be done in the template /etc/pmg/templates/main.cf.in. Whilst I have done this in postfix, I haven't as yet tried it in...

I guess if 'legit' email is scoring 17-19, then whitelisting may be a better approach than tweaking spam rules. I have had some email that I considered not to be spam. However they were so spammy in their style and formatting, I think any content based spam filter would look unkindly on them...

In my case, the emails concerned were spam. I was just looking to understand things a bit better. In your case, you might want to reduce the score (possibly zero) for `KAM_SOMETLD_ARE_BAD_TLD`.

I'm with you on that, especially since the package upgrade now checks for diffs between /etc/pmg/templates & vanilla templates. I did however see this thread, which mentions another approach. Symlinking to distribution templates in /etc/pmg/templates.

IME the error is fatal. pmgconfig will not generate the relevant config file if you try to insert file contents from an absolute path. With that template in place, temporarily remove (or change contents of) /etc/postfix/main.cf and run pmgconfig sync: The output file is not created/updated.

It seems that, in order for INSERT above to work as intended, ABSOLUTE (or REALATIVE) must be true. AFAICS these can't be set in a template file but rather require modifying template constructor in one or more perl scripts of the pmg-api package...

I am not sure it does work. But constructing custom template using the INSERT directive looks like a useful feature. Is there any documentation on using the INSERT/ABSOLUTE options?

I run lm-sensors in a container. I can read the host sensors fine but cannot set thresholds from within the container (I currently have to do that on the pve host). What lxc device node permissions would be needed in order to successfully run sensors -s within the container? The board's sensor...

Here's Proxmox staff member's response to a very similar recent question and where to start reading.

I use PMG in an homelab situation for personal domains. I have played with various all-in-one mail solutions (and learnt much from them) as well as build a mailserver stack from scratch. I now know I prefer the least coupled, modular approach. PMG fits this preference quite well. As dedicated...

Thanks. So the postfix relay restrictions trump any whitelisting defined in mail filtering? That makes sense.
