What specifically in the action_mwl method do you want to add to the report?
If you check the files in /etc/fail2ban/action.d/sendmail* then you will see all the code used for each type of action/report method

First of all thanks for your helping hand.
What I need regarding the sshd blocking action email, is to have full report for banned IP see a sample from my other sarver below:

Unfortunately, I have almost zero python experience, so I can not understand what is necessary to do in order to implement / achive the above result.
Apart of this, my question remain, why the "standard" action / method "action_mwl" does not work?
Many thanks !
ah ok, so you want the whois information, try this one:
[sshd]
enabled = true
filter = sshd
logpath = /var/log/auth.log
action = iptables-multiport[name=sshd, port="22", protocol=tcp]
banned_db[name=sshd, port="22", protocol=tcp]
sendmail-whois-lines[name=sshd, sendername=root@bioeshop.gr, dest=mikek@openforall.com]
Basically the "action" is the name of the conf file in /etc/fail2ban/action.d (minus the .conf extension)

Dear Sir,
yes I change the ssh.local file according to your suggestion and I have it almost as I want. The only thing that is missing, is the copy of related log part that it seems empty as you can see below.

Again, I thank you for your help.
Check under /etc/fail2ban/action.d/sendmail-whois-lines.conf for line logpath = /dev/null
change it to logpath = /var/log/auth.log
(I think that should be the right path for SSH logs by default, assuming it's exactly the same as my Debian setup)

Brilliant, I will make the change later on. My only wondering, because in the etc/fail2ban/jail.d/sshd.local. there is:
logpath = /var/log/auth.log
why doesn't taking into consideration at sendmail-whois-lines.conf ?
Anyway, you really help me very much and I express my gratitude to you.
Cheers!
The logpath defined in the jails (/etc/fail2ban/jail.d/*) specifies where fail2ban looks for events that are happening. When it sees events matching the jail conditions in that logpath then it processes the action associated with that jail
