you should correctly setup your hostname and you dns then.
At least your hostname should resolve to something.

you should use "relay via" and use an account created by your isp if you do not 
want to send emails directly via your server.

May I have question about smart host ?
What is it, how does it work, what do I need, how to configure OPENSMTPD ?

Is it kind of "relay via" ?
Do I need some mail account elsewhere for my OPENSMTD to log in ?
It is hard for me to google out the "idea draft" of smart host)

What I personally do is have a single server in my network able to send emails 
to the public, and all other servers just relay via that server.

Makes handling DKIM/SPF/DMARC easier IMHO

not necessarily but your hostname(1) should resolve to something; you can

As I told you before, set your hostname to something that is resolvable 
(se-gips.interia.eu is in fqdn format but still not resolvable).

Hallo opensmtpd mail list :-)

I must say that I am "email server" greenhorn.
I also do not have much experience in net configuration.

I want to have email server that will allow me to send emails from my linux.
I search internet (sendmail, qmail, exim, postfix, ...) and luckily found 
OPENSMTPD :-)
I have liked it just after seeing one configuration line with: "accept from 
...".
Way of configuring opensmtpd seams to me be modern, simple and easiest of all 
smtp servers :-)

As I wrote I am greenhorn and have problem.

Your  server cannot resolve se-gips domain, check your host name and your

Hi Tomasz,

You already received an answer to your main question, I'll just comment

Could you be more specific, please? What do you mean by "email server"?
Do you want to use it only to send mail or receive, too?

I very much agree with you here here - well, I think we all, on this

If the answer to the above question is "only sent mail from that VM", a
more appropriate configuration would be:

listen on lo

If you are in fact planning on receiving mail on that machine, you can
shorten the above to:

listen on all

You can also limit the listening to inet4 or inet6 family of addresses
if you wish to.

Raf
