[SOLVED] sendmail not working.

knockout_artist · 05-21-2010, 10:38 AM

Hi,

OS = debian

I have my laptop and desktop on same subnet.

From my laptop(FC11) I can send email from command line

Code:

echo  $HOSTNAME | mail -s test my@email.com

But from debian I can't.

I copied same sendmail.cf on both machines.

On debian it sort of hangs for a long time.

I there any way to diagnose the issue?

Thanks

on both machines try- 'echo $hostname | /usr/sbin/sendmail -v my@email.com' and compare the output and post it here, also what do your logs on the debian machine say and is sendmail actually currently running?

This one works(FC)

The problem is on the deferred line, the sendmail daemon doesn't have correct permissions to write to a directory that it needs.

Check /tmp, /var/tmp, /var/spool/mqueue, and /var/mail. Sendmail needs to be able to write to those locations (and it sounds silly but make sure /var or / isn't full)

Code:

test:~# ls  -ld   /var/spool/mqueue
drwxr-s--- 2 smmta smmsp 4096 2010-05-19 06:37 /var/spool/mqueue
test:~# ls  -ld   /var/mail
drwxrwsrwt 2 root mail 4096 2010-05-16 06:25 /var/mail
test:~# ls  -ld   /var/tmp
drwxrwxrwt 2 root root 4096 2010-05-19 06:30 /var/tmp
test:~# df -h 
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda1              18G  4.3G   13G  26% /
tmpfs                 756M     0  756M   0% /lib/init/rw
udev                   10M  704K  9.4M   7% /dev
tmpfs                 756M     0  756M   0% /dev/shm

Every thing is mounted under / , so there is still space there.

Thanks.

What do you get when you 'cat /etc/group | grep 107'? and what are perms on /tmp?

knockout_artist · 05-21-2010, 12:45 PM

Code:

chmod 1777 /var/spool/mqueue

This fixed the problem.

But its still extremely slow compare to FC machine.

rweaver · 05-21-2010, 12:54 PM

Slowness in sendmail I've found 9/10 times is related to dns. Check your resolv.conf settings and make sure your dns servers resolve both your local machine name and the names of machines connecting.

knockout_artist · 06-03-2010, 10:03 AM

Yes. dns had to be corrected.

Its working like a charm now, thanks your your helpl.

Excellent, no problem, glad it's working for you!
