Fail2ban keeps sending emails to root rather than my email

I have the exact same problem on my Debian 10 server. That one is a nasty one as it doesn't really give error messages where you could track it down as there is no real error...

Up there Michael Hampton was giving the right hint. Thank you.

SOLUTION:

Set your 2 emails in every rule where you use it, then it suddenly worked.

Like so:

[sshd]  
enabled   = true
port      = 22
filter    = sshd
logpath   = /var/log/auth.log
sender    = [email protected]
destemail = [email protected]
action    = %(action_mwl)s

It turns out that although I had it in the default declarations , invisibly it didn't get accepted... without giving an error... some random formatting error like an empty line or a comment or so....
