Error 454 - TLS problem ???!

[Friedemann Schorer]

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
smtpd, and /var/log/mail.err shows the following:

> 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
> Jan 28 11:34:14 mail postfix/submission/smtpd[3780]: warning: TLS library problem: error:02001002:system library:fopen:No such file or directory:bss_file.c:402:fopen('/etc/letsencrypt/live/example.org/fullchain.pem;','r'):

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...
