I can´t configure MX(resolv.conf) (rejected mail)

All of the emails are working with the configuration standard of MX Records, but several email servers are rejecting the messages
The mensgem that I am receiving is : (e.g)
-------
Delay reason: SMTP error from remote mailer after initial connection:
host mx.terra.com.br [200.154.55.2]: 450 Client host rejected:
cannot find your hostname, [65.23.158.224]
-------

My hostname is identifying as localhost.
I tried to change Record MX for "mail.mydomain.com" but like this no email is sent nor received. What of doing?

I already altered the file resolv. conf in the following way :

mynameserver 65.23.158.224
mynameserver 65.23.158.241

but even so they continue being rejected my emails

Please somebody help me !!!

You need to change your hostname to one that resolves to an IP#, and that IP# has to resolve back to something (though not necessarily the hostname).

See:

$ man hostname

for how to change your hostname.

How did you set up a DA server with a hostname of localhost? I didn't believe that was possible.

Note to John: it shouldn't be.

Mail rejected.

Hallo,
First of all, you have to have modify the domain, pointing with its A record to your mailserver. (must be a FQDN)

Assume your domain is : thatsit.com,
you should add in DA/DNS administration
: mail: IP nr of domain thatsit.com.
Then, remove pop and old mailsettings from the DNS settings for that domain. Add the right settings: mail.thatsit.com.
(don't forget the dot at the end) and Rank 0-10-20 or so.
Add mail with the IP of your mailserver (That's the IP you bought when you bought the domain), and register (or have it geg'd ) it in DNS.
That should do the job.
succes.

Hi Jeff,

That didn't work. I used the command hostname and he returned the name of the "server. mymaindomain.com.br" .
Stranger is not ?
The only that it is empty is domainname (none)
Should that be like this?

I also made the" dirko" wrote but it didn't work.

Sincerely I don't know more than to try. Do you have some other idea ?

Thanks for Help . :-)

There's no way to tell if your reverse DNS is a problem if you don't post your domain name.

Does the hostname return a fully qualified domain name; similar to "host.example.com", or just an unqualified hostname similar to "host"?

If the latter, then you need to change it to the former.

Hi Jeff . :)

Well, the name of domain is hospedagemtop.com.br
When I use the command hostname returns server. hospedagemtop.com. br (it is name of my server ) .
I don't know what more could be .
:confused: :confused: :confused:

Very much thanks for help and attention.

Your hostname resolves to:

65.23.158.224

and reverse DNS for 65.23.158.224 resolves to tophospedagem.com.br, which is fine.

So there's no problem with reverse DNS.

There's also good MX record for both hospedagem.com.br and for tophospedagem.com.br.

Testing at dnsreport.com turns up no problems.

So I have no idea what the problem is :( ; everything looks good.

i think i can see the error.

In your mailserver, you have to replace "local host" for mail.domainname.ext
If your server has a name, i.e.: MX1.
you could add mx1.mail.domainame.ext.
In your NIC settings, go to advanced an use the DNS settings should be registered.
Your mailserver only should allow smtp authentication and relay only if user is local, or has an account on this server.
Maybe this should solve your problem.

Brazilian ISP lazyness

Hi,

I am also hosting in Brazil and this problem comes up because some Brazilian ISPs (amongst them UOL and Terra) are lazy about updating their DNS tables.

Writing to their webmasters is useless. All you can do is wait. UOL apparently updates once a week on Wednesdays. Haven't found out about Terra yet.

So, just leave the original configurations as they are and... wait.

Cheers,

Marcus
