local host name is not fully qualified

[Rajesh_20]

local host name is not fully qualified fix $j in config file /etc/mail/aliases in UNIX
can anyone help me?

[U.SivaKumar_2]

Hi,

$j is not defined in /etc/mail/aliases . it is defined in /etc/mail/sendmail.cf or /etc/sendmail.cf

edit sendmail.cf and put your domain name at the end of $j macro ( if you use DNS ) or put a dot ( if you dont use DNS )and restart sendmail. hope your problem is solved

Dj$w.mydomain.com

(or)


Dj$w.

Modify the /etc/mail/sendmail.cw which needs a list of all the names by which this host will be known.

YOu can make entry in the file like


.domainname
Then re-start sendmail to
/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start

check those messages dont appear again.

Thanks

If you do not use a DNS server (ie, /etc/hosts is required to resolve your local hostname), then add an alias to /etc/hosts for your local machine which contains a single dot, like this:

12.34.56.78 myhost myhost.


where myhost is your local machine. And make sure that nsswitch.conf has /etc/hosts listed as first or second choice for resolving names (assuming you have the file /etc/resolv.conf). If you don't have resolv.conf, then just make the change to /etc/hosts (and as mentioned before, to sendmail.cf)
