sendmail problem

deepak_9 — Fri, 12 Apr 2002 08:45:32 GMT

Hi,

I am facing a problem while sending a mail using SENDMAIL . For on eserver it's working ok. But for other 3 servers it's giving me an error :-

"unable to qualify the domain-name". I checked for /etc/hosts file the entry seems to be ok. I am specifying the relay server ip in /etc/mail/sendmail.cf file. but it's not going through.

Hi

In etc/hosts put a full stop (period) at end of home server entry.

i.e.

100.100.100.100 this THIS .

It may be that the server is trying to use DNS to resolve rather than the hosts file.

check /etc/mail/service.switch

if it contains
hosts dns files

it will be trying to use DNS in preference to hosts to resolve addresses.

Hi,
Sendmail use the /etc/mail/sendmail.cf config file.
It is here where you have to puit the domain.
That is mean that sendmail can send messages and your machine do not knot what is it own domain.
Edit this file and find the lines:

# my official domain name
Dj$w.terra.es

I hope this help.

Juanma.

If you are using the IP number for the relay in the sendmail.cf file, you might need to enclose it into brackets.
i.e.:
[1.2.3.4] instead of just 1.2.3.4.

check existence and content of /etc/nsswitch.conf

/etc/mail/service.switch is no more used.
