Re: [LI] Questions on mail server setup
Hi,
Thanks for your mail. I've proceeded one more step.
I've enabled my pop server. If I send a UNIX mail, I can receive it in my client.
Now again I'm stuck.
I have setup my my machine as myhost.com
In my email client the pop and SMTP servers are myhost.com.
I sent a mail to myself from the email client it did not get delivered.
After reading logs (/var/logs/maillog) I figured that sendmail received the message but could not deliver. I tried sendmail -q -v. It listed all messages in the queue and said no name found for this recepient. It deffered it in the queue.
Now what do I do ??
Further I started setting up the DNS server.
I have created named.myhost.com.forward and reverse and then restarted the named server. If I try pinging to one of the workstations using the alias name in .forward file, it says host unreacheable. If I use IP address ping goes thru'.
I can send you the forward, reverse and named.boot file. I feel I've must have made some straight forward goof.
Please help.
Thanks and Regards,
Murali
