You need an MX record first...

When a domain name has no MX listed, the A record will be tried next. If that doesn't exist, and the name is a subdomain, the main domain will be tried.

I have an A record for kim2.dodin.org

I just tried sending you an email: bounced (host kim2.dodin.org[213.251.165.214] said: 554 5.7.1 : Relay access denied (in reply to RCPT TO command))

mail sent don't come back, don't come to the dodin.org mx

but can I give a kim2.dodin.org mx without disturbing the main dodin.org mx?

Yes that's perfectly alright. /Per -- Per Jessen, Zürich (15.0°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Per says that can be correct. Till this day I thought that would not work. What I'm sure is that my tests years ago did not work that way, but now, I dunno why.

Are you sure? I think I remember sendmail failing because of that, with a message like host not found.

mail sent don't come back, don't come to the dodin.org mx

but can I give a kim2.dodin.org mx without disturbing the main dodin.org mx? mx is said to be closely tied with domain name, I don't know what subdomain do in the middle (but would like to know :-)

AFAIK, yes, of course. Mail sent to kim2.dodin.org will then be sent to whichever server is listed in the MX register, without ambiguities. It doesn't need to be kim2.dodin.org. - -- Cheers, Carlos E.
