Thank you Tom and Aleksander,
I ran netstat -lnp just to make sure that there is no other service running on port 587,
and in fact there's no one (OS installation is fresh, I don't have other MTAs
installed).
Since Tom can run Dovecot, I suspect that I missed some configuration. Or maybe it is
necessary to enable the process to open lower ports like 587?
Thank you anyway.
Did you check for AVCs?
ausearch -m avc
