$ telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.

Sending mails on Intranet/locally on the same PC without problem.


2)
All mails sent on yahoo.com/gmail.com to this server returned saying users NOT found. However the respective users including Maildir have been created. Mails sent to them on Intranet w/o problem.

Please advise where shall I check? TIA

Hi folks,

Problem half solved.

Now I can send mails to yahoo.com after running;

$ sudo touch /etc/postfix/virtusertable
$ sudo postmap /etc/postfix/virtusertable
$ sudo /etc/init.d/postfix restart


But still can't receive mail. Mails sent on yahoo.com to users on this server returned immediately saying users NOT found..


$ cat /etc/postfix/virtusertable
No printout. It is empty.


$ ls -l /etc/postfix/ | grep virtusertable
-rw-r--r-- 1 root root 0 2007-10-31 21:58 virtusertable
-rw-r--r-- 1 root root 12288 2007-10-31 21:58 virtusertable.db

Sent one mail to 4 users;
satimis
fmaster
administrator
newuser

The mail has not been returned. But it never arrived.

satimis
fmaster
administrator
All have Maildir directory.

Only newuser, a new user, is without Maildir. The trick is here. Maildir will be automatically created if the 1st new mail arrives.

Now where has the mail gone ???



Edit:

Mail returned

This might be a temporary problem. It can take up to 72 hours until DNS changes propagate.

[Maximus_DDT]

Working with UBUNTU 7.04 Feisty as mail server, after a few months without problems the next message appears when i try to send a mail to a account in the server:

Delivery to the following recipient failed permanently:

d.lopez@genes.com.mx

Technical details of permanent failure:
PERM_FAILURE: DNS Error: Domain name not found


What can i do???:confused:

[falko]

There are no DNS records for that domain; there's not even an authoritative DNS server:

Hi Maximus_DDT,


I solved my problem only playing around on the Registrar's Total DNS Control Panel. Please recheck yours on your registrar's website

[Maximus_DDT]

The domain was renew. I chek it twice.

This is the main.cf file on my server. The registered domain is on www.nic.com.mx.

home_mailbox = Maildir/


When I installed the mail server, the main domain is mail.cf.com.mx. Actually, the other alias to genes.com.mx are functional, then when I used d.lopez@genes.com.mx send me the error, but when I used d.lopez@rtequila.com.mx IT WORKS!!

Its a problem with the server or with my internet provider?? :S

Strange. Now there's an MX record, but no A record and no name servers:

I'm very sorry.... I delay so much to comment my situation with the problem.:(

I really appreciate all the comments and "tips", and its very embarrassing to me, but the solution was very dramatic, because my accountant was the responsible of this situation. The DNS was paid on time, but the person on charge to make the payment delayed several days. All the mails are functionally. The mail server its working fine.

I was very mad with that person, and feel so anger.

thanks a lot for the help. I know that in this place I can learn more about linux affairs.

Thanks Again!!:D
