<p>Hi,</p>
<p>I use the current stable 16.1 and didn't setup DKIM yet (but I
want to).</p>
<p>Did you check which TLS and ciphers your system offers to the
world? With "nmap --script ssl-enum-ciphers servername" you'll get
an overview.</p>
<p><br>
</p>
<p>Best regards,</p>
<p>d.<br>

<div>My logs are the same, but I didn't find it odd. Maybe I

<div>On an unrelated note: what version of Kolab do you have and
have you been setting DKIM?<br>

<p>Hi,</p>
<p>unfortunately not.</p>
<p>I hardenen cyrus:</p>
<p>Oct 17 14:20:19 mail02 imaps[13990]: inittls: Loading
hard-coded DH parameters<br>
Oct 17 14:20:19 mail02 imaps[13990]: starttls: TLSv1.2
with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits
reused) no authentication</p>
<p><br>
</p>
<p>but my server still offers TLSv1 and v1.1 plus weak
ciphers.</p>
<p><br>

<div>As far as my understanding is, guam is just a proxy

<br>
I'm new to the list and about to setup a new kolab
system.<br>
<br>
As I'm about to harden all services I got stuck with
tweaking guams tls<br>
settings.<br>
<br>
Is there a way to at least define TLS protocol version
and TLS ciphers?<br>
<br>
<br>
Thanks and best regards,<br>
