mailx not working on Linux,Help needed...Please..?

[redhat70]

Hi,

in our Linux server,DNS is not configured.

Hence mailx is not working...

When I tried to send the mails, it is not sending the mails to the recipient address..

what can be done ?

Any solution please...



$ sendmail -q -v
WARNING: local host name (japan) is not qualified; see cf/README: WHO AM I?

Running /var/spool/mqueue/p61FPoll003674 (sequence 1 of 1)
japan: Name server timeout
<root@japan>... Transient parse error -- message queued for future delivery
japan: Name server timeout
japan: Name server timeout
<root@japan>... Transient parse error -- message queued for future delivery



1.) How to delete the mail queue ?

2.) What is FQDN ?

Generally, in RHEL you have to specificy the DNS manually if you're not using DHCP. If your gateway is a router or configured for it, that is an acceptable IP to use for DNS. Or, you can use whatever DNS your environment is using. If you don't have DNS in your environment, you can always point to a free dns such as 8.8.8.8, which is Google's public DNS.

You can use the system-config-network utility to make these changes. I'm not sure if the changes will survive a reboot or not if you're using DHCP.
Also, make sure your /etc/hosts.conf file is set to allow DNS lookups. Mine says:
multi on
order hosts,bind

An FQDN is a full-qualified-domain-name. Such as server1.mydomain.com

Hi,

mailx works for local users even if dns is not configured, for that you should have sendmail configured properly

mail username@localhost or username@ipaddress

If DNS is configured then you can send mail for users on remote machine using domain name ,, also you can use ipaddress for it

Any solution please...

if sending mail on local host
mailx will work

if remote host
configure DNS

1.) How to delete the mail queue ?

Go to location /var/spool/mqueue and delete or you can tools

2.) What is FQDN ?

fully qaulified domain name
