The sendmail configuration does not work for me.
I configured DNS and then Sendmail.
The procedure I used is:
in /etc/mail/sendmail.mc,
#DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
commented the above line
then
LOCAL_DOMAIN(`host.com')dnl
MASQUERADE_AS(`host.com')dnl
my domail name is set to host.com.

whats the problem
it should work.
Any further help will be appreciated

m4 ? did u compile it?
what's in ur sendmail.cf?

dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
jus try this

m4 is only for frequently update and patch.
try to search file sendmail.cf , edit there and restart sendmail.
good already

i did m4 and generated a sendmail.cf file.
its no offense
and for the comment , i used dnl only not #
everything is set, whats the problem ?

Hi,

I don't know if at this time it would help you, but anyway.

because your are masquerading, did you include "host.com" in the /etc/mail/local-host-names?

get a sample sendmail.cf and files in /etc/mail can solve all the problem.

sailaja - Its not quite clear what you mean by 'the sendmail configuration does not work for me'. There's all sorts of things that could be wrong. For example, sometimes the ISP blocks the smtp data in-bound. So then you can't receive stuff on that port from outside. nmap is a useful for checking on network capabilities.

If you could be very specific about the symptoms of your problem it might help people to see what could be wrong.

Being specific!!!!
ok, all the configuration part is doe. I configured my mail client with this configuration. It says no error. But I can neither send nor recieve mails.

sailu_mvn -

sorry, I didn't mean to be annoying. There are many things that could be wrong. I suggest you divide the possible areas into different parts by differentiating the various symptoms. For example, is this
a) a problem on all networks?
or
b) just on the external network?

You could tell this by sending yourself an email without going through your isp. Do something like
[me@hopeless]$ mail root
This will start the mail program and you can then send some words to root.
Finish the message with a CTRL-D

Now become root
[me@hopeless]$ su - root
and provide the root password.
You can check your mail with a straighforward
[root@hopeless]$ mail
If root has received that message, then sendmail is probably working on your PC.

Another thing to check, as root, are the contents of the maillog. sendmail writes observations to the maillog, and if it is making any complaints you should find them there.
For that you do
[me@hopeless]$ view /var/log/maillog
which will bring up the maillog under vi with no danger of accidentally editing the log.
You can use the character `G' to move to the bottom of the file and see the latest messages.
To leave the editor do
:q


If sendmail is fielding local mail then the problem is probably something to do with your external network and the ISP. If you attach a windows machine to the external network from the same point, can you get & receive email? What email client do you use? If you use something like aol, then you are likely to have problems anyway because aol uses different protocols.

Another possibility is that the sendmail daemon is not actually running. It should be, but you can check with
[me@hopeless] ps -A | grep sendmail
If you get nothing, the daemon is not running.

Ok I wanna use sendmail for sending some emails to my commercial email accounts. I know this script worked on my corporate network but some how on my personal network its not working. The script executes properly but does not send email.

Following is the script i am using:

#!/usr/bin/python

import os
import sys
import re

#Search for the sendmail location on your system.

SENDMAIL = "/usr/sbin/sendmail"

p = os.popen("%s -t" % SENDMAIL, "w")
p.write("To: viklahan@gmail.com\n")
p.write("Subject: Warning: CPU temperature on the DELL laptop is critical\n")
p.write("Please diagnose the problem as soon as possible as it's been observed that the CPU temperature on the DELL laptop is very critical.\n")
p.write("This problem needs to be rectified or else the system might crash.\n")
p.write("This can result is loss of valuable data\n")
sts = p.close()
if sts != 0:
print "Mail has been sent. Now Exiting", sts
when I grab ps -aux output for sendmail, I get the following:

root 4764 0.0 0.2 8744 2524 ? Ss 18:25 0:00 sendmail: MTA: accepting connections

Well, I am pretty sure that its my ISP, i.e. att, so is there is anyway, I can get root to mail me? And also there is nothing in /var/log/messages

Thanks in advance

Hi
U didn't specified your problem in details. Plz provide the OS with version u r using & also send the /etc/hosts file because ur mail server will never work if ur hosts file is misconfigured & also try to send mails to your local users.

Send me the output of the /var/log/mail also. It helps a lot to assure the issue.

Good Luck
