Does not work anymore.

//deinstaled everything
[root@localhost ~]# top -b -n1 | mail -s 'Process snapshot' mymail@mymail.net
/usr/sbin/sendmail: No such file or directory

//reinstaled everything, restart sendmail
[root@localhost ~]# top -b -n1 | mail -s 'Process snapshot' mymail@mymail.net
[root@localhost ~]# /etc/mail/submit.cf: line 544: fileclass: cannot open '/etc/mail/trusted-users': World writable directory
//fixed that with '-o' in /etc/mail/submit.cf, restart sendmail

[root@localhost ~]# top -b -n1 | mail -s 'Process snapshot' mymail@mymail.net

What do you mean by "everything"? When did things stop working? What else changed? Did any behavior change when you uninstalled and reinstalled "everything"?

deinstaled everything means sendmail and one dependent package, which is there by default.

[root@localhost ~]# rpm -qa sendmail
sendmail-8.13.8-2.el5
[root@localhost ~]# netstat -tulpn | grep sendmail
[root@localhost ~]#


hmm looks like it is not running, although look at desktops-s service confuguration says
sendmail (pid 6440) is running...

?

And one more: Did you revert to the default config files? Those are typically not replaced by a re-install.

Using sendmail very rarely so I dont know when it stopped working. The point is thta I ws expecting that if I uninstall and reinstall sendmail it should work, but does not.

Beside the sendmail you also need sendmail-cf and then reconfigure the service described in Deployment Guide's Chapter # 23.
Hint, There is a m4 command in the guide.
Code: Select all
yum install sendmail sendmail-cf sendmail-doc m4


If you use iptables:
Code: Select all
[b]iptables -I INPUT 1 -p tcp -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -I OUTPUT -p tcp -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -I INPUT 1 -p tcp --dport 25 -m state --state NEW -j ACCEPT
iptables -I OUPUT -p tcp --dport 25 -m state --state NEW -j ACCEPT[/b]
