Hi all!

Maybe someone in this list spots the problem?

I installed Kolab Winterfell on Debian Jessie (as mentioned before),
Roundcube shows all the synced mails in my mailbox, but sending mails
doesn't work out - every time I try to do so I get an error 454 from

Jan 28 11:34:14 mail postfix/submission/smtpd[3780]: warning: cannot get RSA certificate from file /etc/letsencrypt/live/example.org/fullchain.pem;: disabling TLS support

The output of 'su -s /bin/bash postfix -c "cat
/etc/letsencrypt/live/example.org/fullchain.pem"' is the content of the
mentioned file, so this shouldn't be a permission problem.

postfix has been added to the group ssl-cert, too.

What the he** could be the problem here?

I'd really appreciate if anyone could give a good hint...
