I've have just installed ZCS 6.0.8 without any problem and opened all needed ports in the SLES 11 SP1 firewall.

MX , hostname and domain seem ok.

/etc/hosts reads
Code:
127.0.0.1 localhost.localdomain localhost
127.0.0.2 mail.unitan.net mail.unitan
200.69.219.57 mail.unitan.net mail.unitan
#hostname returns
Code:
unitan
Is this ok?

domain is
Code:
unitan.net
and #dig unitan.net MX gives
Code:
...
;; ANSWER SECTION
unitan.net. 6026 IN MX 600 mail.unitan.net
...
So I gues MX record is ok too.

Now when I try to connect to https://mail.unitan.net:7780 I get the error

ssl_error-rx_record_too_long

Something must gone wrong with server certificate I think but I don't know how to correct it.

Any idea would be much appreciated,
