Should be here /srv/modoboa/instance/instance/settings.py. Are you sure your installation did end correctly ?

[openaspace]

Yes no errors.
All works.. but the certificate doesn't works.

I have the mail server behind Nginx proxy manager , therefore 80 and 443 are passed by the proxy.... this can be the problem why modoboa doesn't generate correctly the ssl?

I can do it manually?

[Spitfireap]

did you use let's encrypt or self signed on install ?

[openaspace]

git clone https://github.com/modoboa/modoboa-installer

cd modoboa-installer
sudo ./run.py

[Spitfireap]

self signed then.
What's the output of cat /etc/postfix/main.cf | grep sasl please

[openaspace]

Today (after the night) the mail server was not receiving/sending any email...
after the reboot now is working.

root@mail:~# cat /etc/postfix/main.cf | grep sasl
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
smtpd_sasl_security_options = noanonymous
$smtp_sasl_auth_cache_name
$lmtp_sasl_auth_cache_name
permit_sasl_authenticated

Thank you for the support!
