That suggests that the delay is in checking whether komensky.volny.cz is
in local_domains.

However, it is now over 2 years since I last worked on Exim 3. I do not
normally answer detailed questions on it any more. However, I will take
a very brief look at the code ...

Is "komensky.volny.cz" the name of your host? Have you set
primary_hostname in your configuration? If not, Exim will be trying to
find it by calling uname(). What is the output from the command

uname -a

? Does it give your host name as a single component? If so, Exim will be
doing a DNS lookup to find the full name. Maybe that's where the delay
is. Try again with -d11; if I recall correctly, that should also show
you the DNS resolver debugging output.
