UNIX for Dummies Questions & Answers

hi guys

I need to send emails to some accounts

1. I need sendmail up and running right?
2. I need my local sendmail to use an existing SMTP server to send emails (10.x.x.x)? in that case what I need to configure to send emails?
since using mail myaccount@companyame.com is not sending emails to that address

what else is need in my sendmail to send emails out
thanks a lot

Hi
Check with this command is your send mail working or not
# ps -ef | grep sendmail
if it is not working then recheck with

#nslookup -q=mx < domainname.com> ----> use this command to trace the mailhost IP

yeah it is running

Code:

root      3820     1  0 May09 ?        00:00:01 sendmail: accepting connections
smmsp     5571     1  0 May09 ?        00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue
root     32479 12261  0 09:38 pts/1    00:00:00 grep sendmail

using mail -v emailaccount says

Code:

WARNING: local host name (myservername) is not qualified; see cf/README: WHO AM I?
gmail.com: Name server timeout
karlo@gmail.com... Transient parse error -- message queued for future delivery
karlo@gmail.com... queued

let me summarize my issue again since I was not clear

my customer has multiple server but they do not use DNS so there is nothing on resolv.conf

but they opened some communication to a server that is a SMTP server now my questions is these are red hat server 5.0 and I need to send emails. Sendmail is up and running but it fails
with

WARNING: local host name (SRVAMD01) is not qualified; see cf/README: WHO AM I?
lghgbm.net: Name server timeout
l.chacon@lghgbm.net... Transient parse error -- message queued for future delivery
cchacon@gbm.net... queued
You have new mail in /var/spool/mail/root

any idea how to send emails o what I need to change add to my sendmail configuration?

You need to tell sendmail that you are going to use another server as a relay host.

Usually the file can be found in /etc/sendmail/sendmail.cf

Code:

# "Smart" relay host (may be null)
DSxxx.xxx.xxx.xxx

where xxx.xxx.xxx.xxx is the IP address or hostname of the relay server.

Finally, restart the daemon.
