Thanks for answers and help.
At first moment your explanation was good for me. It could looks it is
delay in dns resolving of HELO/EHLO name. But there was still something
which puzzles me.
So I did some tests. I added "warn log_message=testX" in a few places
and sent a few mails using swaks. EHLO always was the same so it should
be in local cache of resolver.
After some debugging I found why format of "H=" is changed. This wasn't
delay in dns resolving. The reason is I used warn with
"verify=reverse_host_lookup" beetwen lines with "log_message".

Next I noticed I had "host_lookup=:" so I changed this to
"host_lookup=*". Solved:)

Thanks again,
Marcin
