Mail server recommendations?

Ok, I have moved mail to new server. postfix + rspamd + dovecot.

In case anyone needs, here is procmail filter for moving mail to Spam folder and marking them read:

Code: 
:0
* ^X-Spam: YES
{
foldername=$HOME/Maildir/.Spam/

:0c
$foldername/

:0
* LASTFOLDER ?? /\/[^/]+$
{ tail=$MATCH }

TRAP="mv $foldername/new/$tail* $foldername/cur/$tail:2,S"

HOST

}
 
What settings do you use for Rspamd?

I currently set up in actions.conf:

Code: 
actions {
    reject = 30; # Reject when reaching this score
    add_header = 6; # Add header when reaching this score
    greylist = null; # Apply greylisting when reaching this score
    }
 
What do you recommend for visualization? Like graphs mail/minute, spam/minute, mail queue, etc?

Command lines for getting numbers are fine, so I could get data to MRTG

Mailscanner with Mailwatch. It is not a smooth install on FBSD unlike Linux(Ubuntu) that it's manual was written for.
 
I now turned off the old mail server. Permanently.

Thank you FreeBSD 5.5, you have served me well. 😥


Ok, graphing feels too complicated and unnecessary, I think I will skip it.

RSPAMD works mostly fine. So far have had only few false positives (newsletters I am interested in) and one spam miss (spam mail written in German).

Still looking for options for whitelisting. Did search for that, but seems complicated in Rspamd:

https://rspamd.com/doc/modules/whitelist.html

https://gist.github.com/ThomasLeister/f41adad98bb46d0c8418de50b5efb4a0

Rspamd own documentation is completely incomprehensible for me. Some kind of DKIM and DMARC - I don't even understand what those are. I know SPF, but most domains don't use it anyway. So I just would like to whitelist e-mail from certain domains or certain e-mail addresses.

DKIM, SPF, DMARC and DANE are recommended for email servers and SSL is recommended for web servers. In fact, most of your outgoing emails will be dropped (i.e. undelivered) without most of them.
They provide identity [by means of electronic signature], protect from phishing, guide from simple attacks (*wares) and a few other things.
 
Fortunately my e-mail server is mostly for incoming mail.

Outgoing mail goes via ISP SMTP server. Without any security or authentication.

When traveling, I am using SMTP2GO for outgoing mail.
