Dear all!
My actual installations with 2023.11 and updates, are wonderful. Certbot gets certificates.
Outlook ist perfecly connected. Grommunio Clients works good. Mails can be sendet and received.
...but...
Thunderbird can only receive mails with ssl/tls - "STARTTLS" no chance.
anyone an idea? or the same problem? my first installation (early 2024) without letsencrypt is possible to get mails from thunderbird with STARTTLS.
regards,
Gerhard
