cannot restart sendmail [solved]

[Majed17]

here is the output:
Code:

gentoo ~ # /etc/init.d/sendmail restart
* Stopping sendmail ...
head: cannot open /var/run/sendmail.pid for reading: No such file or directory
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec] [ !! ]
* ERROR: sendmail failed to stop

when i create the file /var/run/sendmail.pid

it doesn't help:

Code:

gentoo ~ # /etc/init.d/sendmail restart
* Stopping sendmail ...
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec] [ !! ]

here are the permissions:

gentoo ~ # ls -l /var/spool
total 16
Code:

drwxrwx--- 2 smmsp smmsp 4096 Aug 4 15:30 clientmqueue
drwxr-x--- 4 root cron 4096 Jul 31 16:50 cron
drwxrwsr-t 2 root mail 4096 Aug 4 12:45 mail
drwxrwxrwx 2 root mail 4096 Aug 4 15:02 mqueue

i tried unmerging sendmail and reinstalling it but that didn't help.

any idea what to look at?

the solution was to back up to fresh version of gentoo and when installing sendmail change the hosts file to include the hostname of the machine so that sendmail would start quickly.
for the permission error the solution is to,
set the directory /var/spool/mqueue to root:root and then,

i managed to reproduce the problem, when i added some folders to /etc/mail/ then sendmail would not restart saying missing .pid file. i removed the folder and restarted the system and it worked again.
