Dear Debian users,
I would greatly appreciate some help here, as I'm trying to tighten up
my configuration of exim4 in a smarthost way.
My desktop runs Bullseye and performs a few cron tasks who used to send
me by mail the notifications of their successful executions (or not).
I stopped receiving these notifications around late April this year.
But my initial configuration of exim4 was way back, I suppose I just did
something like this at the time :
https://wiki.debian.org/Exim#Smarthost_with_Authentication
My e-mail service provider seems not to accept this anymore so I went to
this chapter :
https://wiki.debian.org/Exim#TLS_and_authentication
... and followed each step except the "Dual stack RSA/ECDSA
configuration" which seemed unnecessary.
Still, a simple :
$ mail -s test my.n...@provider.fr
... ends up to show in # tail -f /var/log/exim4/mainlog :
2021-07-30 10:58:09 1m9OLJ-000cAf-Ss <= my.n...@provider.fr U=rudu
P=local S=461
2021-07-30 10:58:10 1m9OLJ-000cAf-Ss == my.n...@provider.fr R=smarthost
T=remote_smtp_smarthost defer (-37) H=smtpauth.provider.fr
[185.204.xxx.xxx]: TLS session: (certificate verification failed):
certificate invalid
So, when I ran the command :
# bash /usr/share/doc/exim4-base/examples/exim-gencert
... did I miss something that should be there ?
